+PDCurses 2.7 - 2005/12/30
+=========================
+
+INTRODUCTION:
+
+ Hello all. As of a few weeks ago, I'm the new maintainer for PDCurses.
+ Here's a brief summary of changes in this release. (More details are
+ available in the CVS log and trackers on SourceForge.)
+
+NEW FEATURES:
+
+- Functions: delscreen(), getattrs(), has_key(), slk_color(),
+  wcolor_set(), wtimeout().
+
+- Macros: color_set(), mvhline(), mvvline(), mvwgetnstr(), mvwhline(),
+  mvwvline(), timeout(), wresize().
+
+- Stub implementations of terminfo functions (including a term.h).
+
+- More stubs for compatibility: filter(), getwin(), putwin(),
+  noqiflush(), qiflush(), scr_dump(), scr_init(), scr_restore(),
+  scr_set(), use_env(), vidattr(), vidputs().
+
+- The terminal's default colors are used as curses' default colors when
+  the environment variable "PDC_ORIGINAL_COLORS" is set to any value
+  (Win32 only at the moment).
+
+- Simplified build system.
+
+- Replaced PDC_STATIC_BUILD with its opposite, PDC_DLL_BUILD (see .mak
+  files for more info).
+
+- Minimal implementation of color_content() -- no longer a stub.
+
+- Added the remaining ACS defines (ACS_S3, ACS_BBSS, etc.) for
+  DOS/OS2/Win; "enhanced" versions of existing ACS characters used.
+
+- Support for scroll wheels.
+
+- Support for Pacific C.
+
+BUGS FIXED:
+
+- Builds correctly (including demos) on all tested platforms (see
+  below); nearly all compiler warnings have been cleaned up; the ptest
+  demo is built on all platforms; "clean" targets are improved.
+
+- The ability to build ncurses_tests has been restored (see demos dir).
+
+- Line-breakout optimization now defaults to off (equivalent to
+  "typeahead(-1)"), so output is not interrupted by keystrokes (it's
+  supposed to resume on the next refresh(), which wasn't working).
+
+- Implicit wrefresh() in wgetch() was not being invoked in nodelay mode.
+
+- subpad() was erroneously offsetting from the origin coordinates of the
+  parent pad (which are always -1,-1).
+
+- In wborder(), whline(), and wvline(), the current (wattrset) attribute
+  was being used, but not the current background (wbkgd).
+
+- Allow Russian 'r' character ASCII 0xe0 to be returned.
+
+- termattrs() now also returns A_UNDERLINE, A_REVERSE.
+
+- In Win32, with large scrollback buffers set, there was an unwanted
+  "scrollup" effect on startup.
+
+- Revamped keyboard handling for Win32.
+
+- New screen resize method for Win32.
+
+- napms(), delay_output(), etc. now work with Cygwin.
+
+- curs_set(0) wasn't working in Win32 in full-screen (ALT-ENTER) mode --
+  the cursor stayed on.
+
+- The A_REVERSE attribute was broken in XCurses.
+
+- On 64-bit systems, XCurses was ignoring every other keystroke.
+
+- Added focus hints for XCurses.
+
+- Demos (except for tuidemo) once again have their proper titles in
+  XCurses (using Xinitscr() instead of the obsolete XCursesProgramName).
+
+- The 16-bit chtype is a working option again (by removing #define
+  CHTYPE_LONG from curses.h), except in XCurses. It's not recommended;
+  but if your needs are limited, it still works.
+
+- Reset screen size in resetty() under DOS, as in Win32 and OS/2.
+
+- Changes for cursor size under DOS.
+
+- Automatic setting of BIOS mode for CGA under DOS now works.
+
+- The cursor is now always updated in PDC_gotoxy(); this fixes the
+  problem of missing characters in BIOS mode.
+
+- Macros nocbreak(), cbreak(), nocrmode(), crmode(), nodelay(),
+  nl() and nonl() now return OK.
+
+- ERR and OK are now defined as -1 and 0, respectively, for
+  compatibility with other curses implementations -- note that this
+  change is not binary compatible; you'll have to rebuild programs that
+  use shared/dynamic libraries.
+
+- Added "const" to prototypes where appropriate.
+
+- Miscellaneous code cleanup.

+  details were being lost.
+
+NEW FEATURES:
+- Clipboard support now available on DOS platform, but handled internally to the
+  currently running process.
+- new X11 resource; textCursor, allows the text cursor to be specified as a vertical
+  bar, or in the standard horizontal bar. Thanks to Frank Heckenbach for the
+  suggestion.

+------------------------------------------------------------------------
+
+PDCurses 2.3 - 1998/07/09
+=========================
+
+INTRODUCTION:
+
+This release of PDCurses includes the following changes:
+
+- the X11 port is now fully functional
+- the MS Visual C++ Win32 port now includes a DLL
+- both the X11 and Win32 ports support the mouse
+- the slk..() functions are now functional
+- support for scrollbars under X11 are experimental at this stage
+
+The name of the statically built library is pdcurses.lib (or pdcurses.a).  
+The name of the DLL import library (where applicable) is curses.lib.
+
+BUGS FIXED:
+
+some minor bugs were corrected in this release
+
+NEW FUNCTIONS:
+
+slk..() functions
+
+
+NEW COMPILER SUPPORT:
+
+- MS Visual C++ under Win95/NT
+- Watcom C++ under OS/2, Win32 and DOS
+- two EMX ports have been provided:
+  - OS/2 only using OS/2 APIs
+  - OS/2 and DOS using EMX video support routines
+
+Makefiles for each platform/compiler option reside in the platform
+directory.  These all have an extension of .mak.
+
+
+EXTRA OPTIONS:
+
+PDCurses recognises two environment variables which determines the
+initialisation and finalisation behaviour.  These environment variables
+do not apply to the X11 port.
+
+ PDC_PRESERVE_SCREEN
+If this environment variable is set, PDCurses will not clear the screen
+to the default white on black on startup.  This allows you to overlay
+a window over the top of the existing screen background.
+
+ PDC_RESTORE_SCREEN
+If this environment variable is set, PDCurses will take a copy of the
+contents of the screen at the time that PDCurses is started; initscr(),
+and when endwin() is called, the screen will be restored.
+
+
+ACKNOWLEGEMENTS: (for this release)
+
+Chris Szurgot for original Win32 port.
+Gurusamy Sarathy for some updates to the Win32 port.
+Kim Huron for the slk..() functions.

+
+Added Win32 port - original port by Chris Szurgot
+some updates by Mark Hessling
+some updates by Gurusamy Sarathy

+------------------------------------------------------------------------
+
+PDCurses 2.2 - 1995/02/12
+=========================
+
+INTRODUCTION:
+
+	This release of PDCurses has includes a number of major changes:
+		- the portable library functions are now grouped together into
+		  single files with the same arrangement as System V R4 curses.
+		- a panels library has been included. This panels library was
+		  written by Warren Tucker.
+		- quite a few more functions have been supplied by Wade Schauer
+		  and incorporated into release 2.2. Wade also supplied the
+		  support for the Microway NDP C/C++ 32 bit DOS compiler.
+		- the curses datatype has been changed from an unsigned in to
+		  a long. This allows more attributes to be stored as well as
+		  increasing the number of color-pairs from 32 to 64.
+
+BUGS FIXED:
+
+	mvwin() checked the wrong coordinates
+	removed DESQview shadow memory buffer checking
+	bug in curses.h in #define for wstandout()
+	lots of others I can't remember
+
+NEW FUNCTIONS:
+
+	Too many to mention. See intro.man for a complete list of the
+	functions PDCurses now supports.
+
+COMPILER SUPPORT:
+
+	DJGPP 1.12 is now supported. The run-time error that caused
+	programs to crash has been removed.
+
+	emx 0.9a is supported. A program compiled for OS/2 should also
+	work under DOS if you use the VID=EMX switch when compiling. See
+	the makefile for details.
+
+	The Microway NDP C/C++ DOS compiler is now supported. Thanks to 
+	Wade Schauer for this port.
+
+	The Watcom C++ 10.0 DOS compiler is now supported. Thanks to
+	Pieter Kunst for this port.
+
+	The library now has many functions grouped together to reduce the
+	size of the library and to improve the speed of compilation.
+
+	The "names" of a couple of the compilers in the makefile has 
+	changed; CSET2 is now ICC and GO32 is now GCC.
+
+	The Xwindows port is experimental at the moment.
+
+EXTRA OPTIONS:
+
+	One difference between the behaviour of PDCurses and Unix curses
+	is the attributes that are displayed when a character is cleared.
+	Under Unix curses, no attributes are displayed, so 
+	the result is always black. Under PDCurses, these functions clear
+	with the current attributes in effect at the time. With the
+	introduction of the bkgd functions, by default, PDCurses clears
+	using the value set by (w)bkgd(). To have PDCurses behave the
+	same way as it did before release 2.2, compile with -DPDCURSES_WCLR
+
+ACKNOWLEGEMENTS: (for this release)
+
+	Pieter Kunst,David Nugent,Warren Tucker,Darin Haugen,Stefan Strack,
+	Wade Schauer and others who either allerted me to bugs or supplied
+	fixes.
+
+Added more System V R4 functions
+
+Added beta Xwindows port
+
+Changed chtype to long
+
+Incorporated panels library
+
+Support for more and newer versions of compilers
+
+------------------------------------------------------------------------
+
+PDCurses 2.1 - 1993/06/20
+=========================
+
+INTRODUCTION:
+
+	The first thing that obviously needs mentioning is the title above.
+	The current code contains bug fixes for the DOS and OS/2 releases
+	and also includes an alpha release for Unix. The Unix release uses
+	another public domain package (mytinfo) to handle the low-level
+	screen writes. mytinfo was posted to comp.sources.unix (or misc) in
+	December 1992 or January 1993. Unless you are a glutton for punishment
+	I would recommend you avoid the Unix port at this stage.
+	
+	The other major addition to PDCurses is the support for DJGPP (the
+	DOS port of GNU C++). Thanks to David Nugent (davidn@csource.oz.au).
+	
+	Other additions are copywin() function, function debugging support
+	and getting the small and medium memory models to work.
+	The testcurs.c demo program has also been changed significantly and
+	a new demo program, tuidemo, has been added.
+	
+	Some people have suggested including information on where to get
+	dmake from. oak.oakland.edu in /pub/msdos/c
+	
+OTHER NOTES:
+	
+	Under DOS, by default, screen writes to a CGA monitor are done via
+	the video BIOS rather than by direct video memory writes. This is
+	due to the CGA "snow" problem. If you have a CGA monitor and do not
+	suffer from snow, you can compile private\_queryad.c with CGA_DIRECT
+	defined. This will then use cause PDCurses to write directly to the
+	CGA video memory.
+
+	Function debugging: Firstly to get function debugging, you have to
+	compile the library with OPT=N in the makefile. This also turns on
+	compiler debugging. You can control when you want PDCurses to write
+	to the debug file (called trace in the current directory) by using
+	the functions traceon() and traceoff() in your program.
+
+	Microsoft C 6.00 Users note:
+	----------------------------
+	With the addition of several new functions, using dmake to compile 
+	PDCurses now causes the compiler to run "out of heap space in pass 2".
+	Using the 6.00AX version (DOS-Extended) to compile PDCurses fixes
+	this problem; hence the -EM switch.
+
+	Functional changes
+	------------------
+	A few curses functions have been fixed to exhibit their correct 
+	behaviour and make them more functionally portable with System V
+	curses.
+	The functions that have changed are overlay(), overwrite() and
+	typeahead.
+
+	overlay() and overwrite()
+	Both of theses functions in PDCurses 2.0 allowed for one window to
+	be effectively placed on top of another, and the characters in the
+	first window were overlayed or overwritten starting at 0,0 in both
+	windows. This behaviour of these functions was not correct. These
+	functions only operate on windows that physically overlap with
+	respect to the displayed screen. To achieve the same functionality
+	as before, use the new function copywin(). See the manual page for
+	further details.
+
+	typeahead()
+	This function in PDCurses 2.0 effectively checked to see if there
+	were any characters remaining in the keyboard buffer. This is not
+	the behaviour exhibited by System V curses. This function is intended
+	purely to set a flag so that curses can check while updating the
+	physical screen if any keyboard input is pending. To achieve the
+	same effect with typeahead() under PDCurses 2.1 the following code 
+	should be used.
+
+	In place of...
+
+		while(!typeahead(stdin))
+		 {
+			/* do something until any key is pressed... */
+		 }
+
+	use...
+
+		nodelay(stdscr,TRUE); /* getch() to return ERR if no key pending */
+		while(getch() == (ERR))
+		 {
+			/* do something until any key is pressed... */
+		 }

+ACKNOWLEGEMENTS: (in no particlar order)

+	Jason Shumate,Pieter Kunst,David Nugent,Andreas Otte,
+	Pasi Hamalainen,James McLennan,Duane Paulson,Ib Hojme
+	
+	Apologies to anyone I may have left out.

+Added support for djgpp
+
+Added beta Unix version
+
+Added OS/2 DLL support.

+
+PDCurses 2.0 - 1992/11/23
+=========================
+
+INTRODUCTION:
+
+	Well, here it finally is; PDCurses v2.0.
+	
+	PDCurses v2.0 is an almost total rewrite of PCCurses 1.4 done by John
+	'Frotz' Fa'atuai, the previous maintainer.
+	
+	This version has been tested with Microsoft C v6.0, QuickC v2.0 and
+	Borland C++ 2.0 under DOS and Microsoft C v6.0 and TopSpeed c v3.02
+	under OS/2 2.0. Also the library has been compiled successfully with
+	emx 0.8e, C Set/2 and Watcom 9.
+	Most testing was done with the large memory model where applicable.
+	The large memory model is probably the best model to use.
+	
+	The amount of testing has not been as extensive as I would have
+	liked, but demands on releasing a product have outweighed the
+	product's quality. Nothing new with that !!
+	Hopefully with wider circulation, more bugs will be fixed more quickly.
+	
+	I have included just 1 makefile which is suitable for dmake 3.8 for
+	both DOS and OS/2. The makefile does not rely on customisation of the
+	dmake.ini file.
+	
+	If you discover bugs, and especially if you have fixes, please let me
+	know ASAP.
+	
+	The source to the library is distributed as a zip file made with zip
+	1.9. You will need Info-ZIP unzip 5.0 to unzip.
+	Follow the directions below to compile the library.
+
+DIRECTIONS:
+
+	1.Create a new directory in which to unzip pdcurs20.zip. This will
+	  create a curses directory and a number of subdirectories containing
+	  source code for the library and utilities and the documentation.
+
+	2.Make changes to the makefile where necessary:
+	  Change the MODEL or model macro to the appropriate value (if it
+	  applies to your compiler). Use model for Borland compilers.
+
+	  Change any paths in the defined macros to be suitable for your
+	  compiler.
+
+	3.Invoke DMAKE [-e environment_options] [target]
+	
+	  where environment_options are:
+
+		OS (host operating system)
+		COMP (compiler)
+		OPT (optimised version or debug version) - optional. default Y
+		TOS (target operating system) - optional. default OS
+
+		see the makefile for valid combinations
+
+		targets: all, demos, lcursesd.lib, manual...
+		
+		NB. dmake is case sensitive with targets, so those environments
+		that use an upper case model value (eg MSC) MUST specify the
+		library target as for eg. Lcursesd.lib
+
+		The makefile is by default set up for Borland C++. The use of
+		-e environment_options override these defaults. Of you prefer
+		you can just change the defaults in the makefile and invoke it
+		without the -e switch.
+
+OTHER NOTES:
+
+	The documentation for the library is built into each source file,
+	a couple of specific doc files and the header files. A program is
+	supplied (manext) to build the manual. This program gets compiled
+	when you build the documentation.
+	
+	To generate the library response file correctly, I had to write a
+	quick and dirty program (buildlrf) to achive this. Originally the
+	makefiles just had statements like: "echo -+$(OBJ)\$* & >> $(LRF)"
+	which appended a suitable line to the response file. Unfortunately
+	under some combinations of makefiles and command processors (eg.
+	nmake and 4DOS) the & would get treated as stderr and the echo
+	command would fail.
+	
+	The original source for PDCurses that I received from the previous
+	maintainer contained support for the FLEXOS operating system. Not
+	having access to it, I could not test the changes I made so its
+	support has fallen by the wayside. If you really need to have PDCurses
+	running under FLEXOS, contact me and I will see what can be arranged.
+	
+	Under DOS, by default, screen writes to a CGA monitor are done via
+	the video BIOS rather than by direct video memory writes. This is
+	due to the CGA "snow" problem. If you have a CGA monitor and do not
+	suffer from snow, you can compile private\_queryad.c with CGA_DIRECT
+	defined. This will then use cause PDCurses to write directly to the
+	CGA video memory.
+
+COMPILER-SPECIFIC NOTES:
+
+	Microsoft C
+	-----------
+	It is possible with MSC 6.0 to build the OS/2 libraries and demo
+	programs from within DOS. This is the only case where it is possible
+	to specifiy the value of TOS on the command line to be OS2 and the
+	value of OS be DOS.
+
+	C Set/2
+	-------
+	I have only tested the library using the migration libraries. I doubt
+	that the demo programs will work without them.
+
+	emx
+	---
+	Testing has been done with 0.8e of emx together with the 16_to_32
+	libraries.
+	The emx\lib directory should include the vio32.lib and kbd32.lib
+	libraries from the 16_to_32 package.
+
+BUGS and UNFINISHED BUSINESS:
+
+	PDC_set_ctrl_break() function does not work under OS/2.
+	win_print() and PDC_print() do not work under OS/2.
+	The file todo.man in the doc directory also lists those functions of
+	System V 3.2 curses not yet implemented. Any volunteers ?
+
+ACKNOWLEGEMENTS:
+
+	John 'Frotz' Fa'atuai, the previous maintainer for providing an
+	excellent base for further development.
+	John Burnell (johnb@kea.am.dsir.govt.nz), for the OS/2 port.
+	John Steele, Jason (finally NOT a John) Shumate....
+	for various fixes and suggestions.
+	Eberhardt Mattes (author of emx) for allowing code based on his
+	C library to be included with PDCurses.
+	Several others for their support, moral and actual.
+
+Changed #if to #ifdef/#if defined to make it easier to add new 
+platforms/compilers.
+
+Added System V colour support.
+
+Added OS/2 port.

+
+PDCurses 2.0Beta - 1991/12/21
+=============================
+
+Changed back from short to int. (int is the correct size for the default 
+platform. Short might be too short on some platforms. This is more 
+portable. I, also, made this mistake.)
+
+Many functions are now macros.  If you want the real thing, #undef the 
+macro. (X/Open requirement.)
+
+Merged many sources into current release.
+
+Added many X/Open routines (not quite all yet).
+
+Added internal documentation to all routines.
+
+Added a HISTORY file to the environment.
+
+Added a CONTRIB file to the environment.
+
+------------------------------------------------------------------------
+
+PDCurses 1.5Beta - 1990/07/14
+=============================
+
+Added many levels of compiler support. Added mixed prototypes for all 
+"internal" routines. Removed all assembly language.  Added EGA/VGA 
+support.  Converted all #ifdef to #if in all modules except CURSES.H and 
+CURSPRIV.H. Always include ASSERT.H.  Added support for an external 
+malloc(), calloc() and free(). Added support for FAST_VIDEO 
+(direct-memory writes). Added various memory model support (for 
+FAST_VIDEO). Added much of the December 1988 X/Open Curses 
+specification.

+
+PCCURSES 1.4 - 1990/01/14
+=========================
+
+  This is the release note for the fifth version of PCcurses, v.1.4.
+Below this note, the release notes for v.1.0 - v.1.3 are included. Read
+those first.
+
+  In PCcurses v.1.4, both portability improvements and bugfixes have
+been made. The files have been changed to allow lint-free compilation
+with MicroSoft 'C' v.5.1, and with Turbo 'C' v.2.0. The source should
+still compile without problems on older compilers, although this has
+not been verified.
+
+  The makefiles have been changed to suit both the public release and
+the author, who maintains a special kind of libraries for himself. In
+the case of MicroSoft 'C', changes were done in the makefile to lower
+the warning level to 2 (was 3). This was to avoid ANSI warnings which
+are abundant because PCcurses does not attempt to follow strict ANSI
+'C' standard.
+
+  BUG FIXES FROM V.1.3 TO V.1.4:
+
+  !!!IMPORTANT CHANGE!!!
+
+  The definitions for OK and ERR in curses.h were exchanged. This was
+done to be more consistent with UNIX versions. Also, it permits func-
+tions like newwin() and subwin() to return 0 (=NULL) when they fail
+due to memory shortage. This incompatibility with UNIX curses was
+pointed out by Fred C. Smith. If you have tested success/failure by
+comparisons to anything other than ERR and OK, your applications will
+need to be be changed on that point. Sorry... but presumably most of
+you used the symbolic constants?
+
+  (END OF IMPORTANT CHANGE)
+
+  Fred also pointed out a bug in the file update.c. The bug caused the
+first character printed after 'unauthorized' screen changes (like du-
+ring a shell escape, for example) to be placed at the wrong screen posi-
+tion. This happened even if the normal precautions (clear / touch / re-
+fresh) were taken. The problem has now been fixed.
+
+  PCcurses is currently also being used on a 68000 system with hard-
+coded ESCape sequences for ANSI terminals. However, int's used by the
+68000 C compiler are 32 bits. Therefore int's have been turned into
+short's wherever possible in the code (otherwise all window structures
+occupy twice as much space as required on the 68000). This does not
+affect PC versions since normally both int's and short's are 16 bits
+for PC C compilers.
+
+  At some places in the source code there are references made to the
+68000 version. There are also a makefile, a curses68.c file, and a
+curses68.cmd file. These are for making, low-level I/O, and linking
+commands when building the 68000 version. These files are probably
+useful to no-one but the author, since it is very specific for it's
+special hardware environment. Still in an effort to keep all curses-
+related sources in one place they are included. Note however that
+PCcurses will not officially support a non-PC environment.
+
+  The file cursesio.c, which was included in the package at revision
+level 1.2, and which was to be an alternative to the cursesio.asm
+file, has been verified to behave incorrectly in the function
+_curseskeytst(). The problem was that the value of 'cflag' does not
+contain the proper data for the test that is attempted. Furthermore,
+neither Turbo'C' or MicroSoft'C' allows any way to return the data
+that is needed, and consequently you should not use cursesio.c. The
+best solution is to simply use the ASM version. In v.1.2 and v.1.3,
+the user could edit the makefile to select which version he wanted to
+use. The makefiles in v.1.4 have removed this possiblity forcing the
+use of the ASM file, and cursesio.c has been dropped from the distri-
+bution.
+
+  A bug in the wgetstr() function caused PCcurses to echo characters
+when reading a keyboard string, even if the echo had been turned off.
+Thanks to Per Foreby at Lund University, Sweden, for this. Per also
+reported bugs concerning the handling of characters with bit 8 set.
+Their ASCII code were considered as lower than 32, so they were
+erased etc. like control characters, i.e. erasing two character posi-
+tions. The control character test was changed to cope with this.
+
+  The overlay() and overwrite() functions were changed so that the
+overlaying window is positioned at it's 'own' coordinates inside the
+underlying window (it used to be at the underlying window's [0,0]
+position). There is some controversy about this - the documentation
+for different curses versions say different things. I think the
+choice made is the most reasonable.
+
+  The border() and wborder() functions were changed to actually draw
+a border, since this seems to be the correct behaviour of these func-
+tions. They used to just set the border characters to be used by
+box(). These functions are  not present in standard BSD UNIX curses.
+
+  The subwin() function previously did not allow the subwindow to be
+as big as the original window in which it was created. This has now
+been fixed. There was also the problem that the default size (set by
+specifying numlines or numcols (or both) as 0 made the resulting
+actual size 1 line/column too small.
+
+  There were a few spelling errors in function names, both in the
+function declarations and in curses.h. This was reported by Carlos
+Amaral at INESC in Portugal. Thanks! There was also an unnecessary
+(but harmless) parameter in a function call at one place.
+
+Window origin mod in overlay() and overwrite(), on public (and very 
+reasonable) request. Swapped #define'd values of OK and ERR; OK now 1, 
+and ERR is 0/NULL. Conforms better to UNIX versions. borderchars[] 
+removed from WINDOW struct since the border() functions were redefined. 
+Use of short wherever possible. Portability improvements, mispelled name 
+of [w]setscrreg().
+
+------------------------------------------------------------------------
+
+PCCURSES 1.3 - 1988/10/05
+=========================
+
+  This is the release note for the fourth version of PCcurses, v.1.3.
+Below this note, the release notes for v.1.0, v.1.1 and v.1.2 are in-
+cluded. Read those first.
+
+  The file 'border.c' is now included. It allows you to explicitely speci-
+fy what characters should be used as box borders when the box() functions
+are called. If the new border characters are non-0, they override the bor-
+der characters specified in the box() call. In my understanding, this func-
+tionality is required for AT&T UNIX sV.3 compatibility. Thanks for this
+goes to Tony L. Hansen (hansen@pegasus.UUCP) for posting an article about
+it on UseNet (newsgroup comp.unix.questions; his posting was not related
+at all to PCcurses).
+
+  The only other difference between v.1.2 and v.1.3 is that the latter has
+been changed to avoid warning diagnostics if the source files are compiled
+with warning switches on (for MicroSoft this means '-W3', for Turbo'C' it
+means '-w -w-pro'). Of these, the Turbo'C' warning check is clearly to be
+used rather than MicroSoft, even if neither of them comes even close to a
+real UNIX 'lint'. Some of the warnings in fact indicated real bugs, mostly
+functions that did not return correct return values or types.
+
+  The makefiles for both MSC and TRC have been modified to produce warning
+messages as part of normal compilation.
+
+All modules lint-checked with MSC '-W3' and turbo'C' '-w -w-pro' 
+switches. Support for border(), wborder() functions.
+
+------------------------------------------------------------------------
+
+PCCURSES 1.2 - 1988/10/02
+=========================
+
+  This is the release note for the third version of PCcurses, v.1.2.
+Below this note, the release notes for v.1.0 and v.1.1 are included. Read
+those first.
+
+  The changes from v.1.1 to v.1.2 are minor. The biggest change is that there
+was a bug related to limiting the cursor movement if the application tried to
+move it outside the screen (something that should not be done anyway). Such
+erronous application behaviour is now handled appropriately.
+
+  All modules have been changed to have a revison string in them, which makes
+it easier to determine what version is linked into a program (or what library
+version you have).
+
+  There is now a 'cursesio.c' file. That file does the same as 'cursesio.asm'
+(i.e. it provides the interface to the lower-level system I/O routines). It
+is written in 'C' and thus it is (possibly) more portable than the assembler
+version (but still not so portable since it uses 8086 INT XX calls directly).
+When one creates new curses libraries, one chooses whether to use the assem-
+bler or the 'C' version of cursesio. The choice is made by commenting out the
+appropriate dependencies for cursesio.obj, near the end of the makefiles.
+
+  There is now a 'setmode.c' file. That file contains functions that save and
+restore terminal modes. They do it into other variables than do savetty() and
+resetty(), so one should probably use either savetty()/resetty() or the new
+functions only - and not mix the both ways unless one really knows what one
+does.
+
+  Diff lists vs v.1.0 are no longer included in the distribution. The make
+utility still is. PCcurses v.1.2 still compiles with MicroSoft 'C' v.4.0,
+and with Borland Turbo 'C' v.1.0. There is as far as I know no reason to be-
+lieve that it does not compile under MicroSoft 'C' v.3.0 and 5.x, or Turbo-
+'C' v.1.5, but this has not been tested.
+
+  There are two makefile's included, one for MicroSoft 'C', one for Turbo-'C'.
+They are both copies of my personal makefile's, and as such they reflect the
+directory structure on my own computer. This will have to be changed before
+you run make. Check $(INCDIR) and $(LIBDIR) in particular, and make the choice
+of ASM or 'C' cursesio version as mentioned above (the distribution version
+uses the 'C version of cursesio).
+
+  The manual file (curses.man) has been changed at appropriate places.
+
+  I would like to thank the following persons for their help:
+
+  	Brandon S. Allbery (alberry@ncoast.UUCP)
+		for running comp.binaries.ibm.pc (at that time)
+		and comp.source.misc.
+
+	Steve Balogh (Steve@cit5.cit.oz.AU)
+  		for writing a set of manual pages and posting
+		them to the net.
+
+	Torbjorn Lindh
+		for finding bugs and suggesting raw
+		character output routines.
+
+	Nathan Glasser (nathan@eddie.mit.edu)
+  		for finding and reporting bugs.
+
+	Ingvar Olafsson (...enea!hafro!ingvar)
+  		for finding and reporting bugs.
+
+	Eric Rosco (...enea!ipmoea!ericr)
+  		for finding and reporting bugs.
+
+	Steve Creps (creps@silver.bacs.indiana.edu)
+  		for doing a lot of work - among others
+		posting bug fixes to the net, and writing
+		the new cursesio.c module.
+
+	N. Dean Pentcheff (dean@violet.berkeley.edu)
+  		for finding bugs and rewriting cursesio.asm
+		for Turbo 'C' 1.5.
+
+  Finally, Jeff Dean (parcvax,hplabs}!cdp!jeff)
+  		     (jeff@ads.arpa)
+	has had a shareware version of curses deliverable since
+	about half a year before I released PCcurses 1.0 on Use-
+	Net. He is very concerned about confusion between the two
+	packages, and therefore any references on the network
+	should make clear whether they reference Dean's PCcurses
+	or Larsson's PCcurses.
+
+Rcsid[] string in all modules, for maintenance.
+
+Support (by #ifdef UCMASM) for uppercase-only assembly routine names. If 
+UCMASM if defined, all assembler names are #defined as upper case. Not 
+needed if you do "MASM /MX. Also missing declaration of cursesscroll(). 
+Fixes thanks to N.D. Pentcheff

+------------------------------------------------------------------------
+
+PCCURSES 1.1 - 1988/03/06
+=========================
+
+  This is the release note for the second version of PCcurses, v.1.1.
+Below this note, the release note for v.1.0 is included. Read that first.
+The changes from v.1.0 to v.1.1 are minor. There are a few bug fixes, and
+new (non-portable) functions for verbatim IBM character font display have
+been added (in charadd.c and charins.c). The manual file (curses.man) has
+been changed at appropriate places.
+
+  In the file v10tov11.dif there are listings of the differencies between
+version 1.0 and 1.1. The diff listings are in UNIX diff(1) format.
+
+  Version 1.1 compiles with Turbo 'C' v.1.0, as well as MicroSoft 'C' v.3.0
+and v.4.0. On the release disk there is a make.exe utility which is very simi-
+lar to UNIX make (If the package was mailed to you, the make utility will be
+in uuencoded format - in make.uu - and must be uudecoded first). It is much
+more powerful than MicroSoft's different MAKE'S; the latter ones will NOT ge-
+nerate libraries properly if used with the PCcurses makefiles.
+
+  There are three makefiles:
+
+	makefile		generic MSC 3.0 makefile
+	makefile.ms		MSC 4.0 makefile
+	makefile.tc		Turbo 'C' 1.0 makefile
+
+  To make a library with for example Turbo 'C', make directories to hold .H
+and .LIB files (these directories are the 'standard places'), edit makefile.tc
+for this, and type
+
+	make -f makefile.tc all
+
+and libraries for all memory models will be created in the .LIB directory,
+while the include files will end up in the .H directory. Also read what is
+said about installation below!
+
+'Raw' output routines, revision info in curses.h.

+------------------------------------------------------------------------
+
+PCCURSES 1.0 - 1987/08/24
+=========================
+
+  This is the release notes for the PCcurses v.1.0 cursor/window control
+package. PCcurses offers the functionality of UNIX curses, plus some
+extras. Normally it should be possible to port curses-based programs from
+UNIX curses to PCcurses on the IBM PC without changes. PCcurses is a port/
+rewrite of Pavel Curtis' public domain 'ncurses' package. All the code has
+been re-written - it is not just an edit of ncurses (or UNIX curses). I
+mention this to clarify any copyright violation claims. The data struc-
+tures and ideas are very similar to ncurses. As for UNIX curses, I have
+not even seen any sources for it.
+
+ For an introduction to the use of 'curses' and it's derivatives, you
+should read 'Screen Updating and Cursor Movement Optimization: A Library
+Package' by Kenneth C. R. C. Arnold, which describes the original Berkely
+UNIX version of curses. It is available as part of the UNIX manuals. The
+other source of information is 'The Ncurses Reference Manual' by Pavel
+Curtis. The latter is part of Curtis' ncurses package.
+
+  The only other documentation provided is a 'man' page which describes
+all the included functions in a very terse way. In the sources, each
+function is preceded by a rather thourough description of what the
+function does. I didn't have time to write a nice manual/tutorial - sorry.
+
+  PCcurses is released as a number of source files, a man page, and a make
+file. A uuencoded copy of a 'make' utility, and a manpage for the 'make' is
+also provided to make it easier to put together PCcurses libraries. Even if
+you are not interested in PCcurses, it may be worthwhile to grab the make.
+
+  The makefile assumes the presence of the MicroSoft 'C' compiler (3.0 or
+4.0), MicroSoft MASM and LIB, plus some MS-DOS utilities. The reason for
+supplying MAKE.EXE is that the MicroSoft 'MAKE:s' are much inferior to a
+real UNIX make. The supplied make is a port of a public domain make, pub-
+lished on UseNet. It is almost completely compatible with UNIX make. When
+generating the curses libraries, the makefile will direct make to do some
+directory creating and file copying, and then re-invoke itself with new
+targets. The workings of the makefile are not absolutely crystal clear at
+first sight... just start it and see what it does.
+
+  For portability, the curses libraries depend on one assembler file for
+access to the BIOS routines. There is no support for the EGA, but both
+CGA, MGA, and the HGA can be used. The libraries are originally for Micro-
+Soft 'C', but all C modules should be portable right away. In the assembler
+file, segment names probably need to be changed, and possibly the parameter
+passing scheme. I think Turbo C will work right away - as far as I under-
+stand, all it's conventions are compatible with MicroSoft C.
+
+  There are some parts left out between ncurses and PCcurses. One is the
+support for multiple terminals - not very interesting on a PC anyway. Be-
+cause we KNOW what terminal we have, there is no need for a termcap or
+termio library. PCcurses also has some things that neither curses nor
+ncurses have. Compared to the original UNIX curses, PCcurses has lots
+of extras.
+
+  The BIOS routines are used directly, which gives fast screen updates.
+PCcurses does not do direct writes to screen RAM - in my opinion it is
+a bit ugly to rely that much on hardware compatibility. Anyone could fix
+that, of course...
+
+  One of the more serious problems with PCcurses is the way in which nor-
+mal, cbreak, and raw input modes are done. All those details are in the
+'charget' module - I do raw I/O via the BIOS, and perform any buffering
+myself. If an application program uses PCcurses, it should do ALL it's
+I/O via PCcurses calls, otherwise the mix of normal and PCcurses I/O may
+mess up the display. I think my code is reasonable... comments are welcome,
+provided you express them nicely...
+
+  To install, copy all files to a work directory, edit 'makefile' to define
+the standard include and library file directory names of your choice (these
+directories must exist already, and their path names must be relative to the
+root directory, not to the current one). You must also run uudecode on
+make.uu, to generate MAKE.EXE. You can do that on your PC, if you have
+uudecode there, otherwise you can do it under UNIX and do a binary transfer
+to the PC. When you have MAKE.EXE in your work directory (or in your /bin
+directory), type make.
+
+  Make will now create 4 sub-directories (one for each memory model), copy
+some assembler include files into them, copy two include files to your
+include directory, CHDIR to each sub-directory and re-invoke itself with
+other make targets to compile and assemble all the source files into the
+appropriate directories. Then the library manager is run to create the
+library files in your desired library directory. Presto!
+
+  If you only want to generate a library for one memory model, type 'make
+small', 'make large', etc. The name of the memory model must be in lower
+case, like in the makefile.
+
+  I think the package is fairly well debugged - but then again, that's
+what I always think. It was completed in May-87, and no problems found
+yet. Now it's your turn... Comments, suggestions and bug reports and
+fixes (no flames please) to
+

-PDCurses 2.7 - 2005/12/30
-=========================
-
-INTRODUCTION:
-
- Hello all. As of a few weeks ago, I'm the new maintainer for PDCurses.
- Here's a brief summary of changes in this release. (More details are
- available in the CVS log and trackers on SourceForge.)
-
-NEW FEATURES:
-
-- Functions: delscreen(), getattrs(), has_key(), slk_color(),
-  wcolor_set(), wtimeout().
-
-- Macros: color_set(), mvhline(), mvvline(), mvwgetnstr(), mvwhline(),
-  mvwvline(), timeout(), wresize().
-
-- Stub implementations of terminfo functions (including a term.h).
-
-- More stubs for compatibility: filter(), getwin(), putwin(),
-  noqiflush(), qiflush(), scr_dump(), scr_init(), scr_restore(),
-  scr_set(), use_env(), vidattr(), vidputs().
-
-- The terminal's default colors are used as curses' default colors when
-  the environment variable "PDC_ORIGINAL_COLORS" is set to any value
-  (Win32 only at the moment).
-
-- Simplified build system.
-
-- Replaced PDC_STATIC_BUILD with its opposite, PDC_DLL_BUILD (see .mak
-  files for more info).
-
-- Minimal implementation of color_content() -- no longer a stub.
-
-- Added the remaining ACS defines (ACS_S3, ACS_BBSS, etc.) for
-  DOS/OS2/Win; "enhanced" versions of existing ACS characters used.
-
-- Support for scroll wheels.
-
-- Support for Pacific C.
-
-BUGS FIXED:
-
-- Builds correctly (including demos) on all tested platforms (see
-  below); nearly all compiler warnings have been cleaned up; the ptest
-  demo is built on all platforms; "clean" targets are improved.
-
-- The ability to build ncurses_tests has been restored (see demos dir).
-
-- Line-breakout optimization now defaults to off (equivalent to
-  "typeahead(-1)"), so output is not interrupted by keystrokes (it's
-  supposed to resume on the next refresh(), which wasn't working).
-
-- Implicit wrefresh() in wgetch() was not being invoked in nodelay mode.
-
-- subpad() was erroneously offsetting from the origin coordinates of the
-  parent pad (which are always -1,-1).
-
-- In wborder(), whline(), and wvline(), the current (wattrset) attribute
-  was being used, but not the current background (wbkgd).
-
-- Allow Russian 'r' character ASCII 0xe0 to be returned.
-
-- termattrs() now also returns A_UNDERLINE, A_REVERSE.
-
-- In Win32, with large scrollback buffers set, there was an unwanted
-  "scrollup" effect on startup.
-
-- Revamped keyboard handling for Win32.
-
-- New screen resize method for Win32.
-
-- napms(), delay_output(), etc. now work with Cygwin.
-
-- curs_set(0) wasn't working in Win32 in full-screen (ALT-ENTER) mode --
-  the cursor stayed on.
-
-- The A_REVERSE attribute was broken in XCurses.
-
-- On 64-bit systems, XCurses was ignoring every other keystroke.
-
-- Added focus hints for XCurses.
-
-- Demos (except for tuidemo) once again have their proper titles in
-  XCurses (using Xinitscr() instead of the obsolete XCursesProgramName).
-
-- The 16-bit chtype is a working option again (by removing #define
-  CHTYPE_LONG from curses.h), except in XCurses. It's not recommended;
-  but if your needs are limited, it still works.
-
-- Reset screen size in resetty() under DOS, as in Win32 and OS/2.
-
-- Changes for cursor size under DOS.
-
-- Automatic setting of BIOS mode for CGA under DOS now works.
-
-- The cursor is now always updated in PDC_gotoxy(); this fixes the
-  problem of missing characters in BIOS mode.
-
-- Macros nocbreak(), cbreak(), nocrmode(), crmode(), nodelay(),
-  nl() and nonl() now return OK.
-
-- ERR and OK are now defined as -1 and 0, respectively, for
-  compatibility with other curses implementations -- note that this
-  change is not binary compatible; you'll have to rebuild programs that
-  use shared/dynamic libraries.
-
-- Added "const" to prototypes where appropriate.
-
-- Miscellaneous code cleanup.

-
-PDCurses 2.3 - 1998/07/09
-=========================
-
-INTRODUCTION:
-
-This release of PDCurses includes the following changes:
-
-- the X11 port is now fully functional
-- the MS Visual C++ Win32 port now includes a DLL
-- both the X11 and Win32 ports support the mouse
-- the slk..() functions are now functional
-- support for scrollbars under X11 are experimental at this stage
-
-The name of the statically built library is pdcurses.lib (or pdcurses.a).  
-The name of the DLL import library (where applicable) is curses.lib.
-
-BUGS FIXED:
-
-some minor bugs were corrected in this release
-
-NEW FUNCTIONS:
-
-slk..() functions
-
-
-NEW COMPILER SUPPORT:
-
-- MS Visual C++ under Win95/NT
-- Watcom C++ under OS/2, Win32 and DOS
-- two EMX ports have been provided:
-  - OS/2 only using OS/2 APIs
-  - OS/2 and DOS using EMX video support routines
-
-Makefiles for each platform/compiler option reside in the platform
-directory.  These all have an extension of .mak.
-
-
-EXTRA OPTIONS:
-
-PDCurses recognises two environment variables which determines the
-initialisation and finalisation behaviour.  These environment variables
-do not apply to the X11 port.
-
- PDC_PRESERVE_SCREEN
-If this environment variable is set, PDCurses will not clear the screen
-to the default white on black on startup.  This allows you to overlay
-a window over the top of the existing screen background.
-
- PDC_RESTORE_SCREEN
-If this environment variable is set, PDCurses will take a copy of the
-contents of the screen at the time that PDCurses is started; initscr(),
-and when endwin() is called, the screen will be restored.
-
-
-ACKNOWLEGEMENTS: (for this release)
-
-Chris Szurgot for original Win32 port.
-Gurusamy Sarathy for some updates to the Win32 port.
-Kim Huron for the slk..() functions.
-Florian Grosse Coosmann for some bug fixes.
-Esa Peuha for reducing compiler warnings.
-Augustin Martin Domingo for patches to X11 port to enable accented 
- characters.

-
-PDCurses 2.2 - 1995/02/12
-=========================
-
-INTRODUCTION:
-
-	This release of PDCurses has includes a number of major changes:
-		- the portable library functions are now grouped together into
-		  single files with the same arrangement as System V R4 curses.
-		- a panels library has been included. This panels library was
-		  written by Warren Tucker.
-		- quite a few more functions have been supplied by Wade Schauer
-		  and incorporated into release 2.2. Wade also supplied the
-		  support for the Microway NDP C/C++ 32 bit DOS compiler.
-		- the curses datatype has been changed from an unsigned in to
-		  a long. This allows more attributes to be stored as well as
-		  increasing the number of color-pairs from 32 to 64.
-
-BUGS FIXED:
-
-	mvwin() checked the wrong coordinates
-	removed DESQview shadow memory buffer checking
-	bug in curses.h in #define for wstandout()
-	lots of others I can't remember
-
-NEW FUNCTIONS:
-
-	Too many to mention. See intro.man for a complete list of the
-	functions PDCurses now supports.
-
-COMPILER SUPPORT:
-
-	DJGPP 1.12 is now supported. The run-time error that caused
-	programs to crash has been removed.
-
-	emx 0.9a is supported. A program compiled for OS/2 should also
-	work under DOS if you use the VID=EMX switch when compiling. See
-	the makefile for details.
-
-	The Microway NDP C/C++ DOS compiler is now supported. Thanks to 
-	Wade Schauer for this port.
-
-	The Watcom C++ 10.0 DOS compiler is now supported. Thanks to
-	Pieter Kunst for this port.
-
-	The library now has many functions grouped together to reduce the
-	size of the library and to improve the speed of compilation.
-
-	The "names" of a couple of the compilers in the makefile has 
-	changed; CSET2 is now ICC and GO32 is now GCC.
-
-	The Xwindows port is experimental at the moment.
-
-EXTRA OPTIONS:
-
-	One difference between the behaviour of PDCurses and Unix curses
-	is the attributes that are displayed when a character is cleared.
-	Under Unix curses, no attributes are displayed, so 
-	the result is always black. Under PDCurses, these functions clear
-	with the current attributes in effect at the time. With the
-	introduction of the bkgd functions, by default, PDCurses clears
-	using the value set by (w)bkgd(). To have PDCurses behave the
-	same way as it did before release 2.2, compile with -DPDCURSES_WCLR
-
-ACKNOWLEGEMENTS: (for this release)
-
-	Pieter Kunst,David Nugent,Warren Tucker,Darin Haugen,Stefan Strack,
-	Wade Schauer and others who either allerted me to bugs or supplied
-	fixes.

-
-PDCurses 2.1 - 1993/06/20
-=========================
-
-INTRODUCTION:
-
-	The first thing that obviously needs mentioning is the title above.
-	The current code contains bug fixes for the DOS and OS/2 releases
-	and also includes an alpha release for Unix. The Unix release uses
-	another public domain package (mytinfo) to handle the low-level
-	screen writes. mytinfo was posted to comp.sources.unix (or misc) in
-	December 1992 or January 1993. Unless you are a glutton for punishment
-	I would recommend you avoid the Unix port at this stage.
-	
-	The other major addition to PDCurses is the support for DJGPP (the
-	DOS port of GNU C++). Thanks to David Nugent (davidn@csource.oz.au).
-	
-	Other additions are copywin() function, function debugging support
-	and getting the small and medium memory models to work.
-	The testcurs.c demo program has also been changed significantly and
-	a new demo program, tuidemo, has been added.
-	
-	Some people have suggested including information on where to get
-	dmake from. oak.oakland.edu in /pub/msdos/c
-	
-OTHER NOTES:
-	
-	Under DOS, by default, screen writes to a CGA monitor are done via
-	the video BIOS rather than by direct video memory writes. This is
-	due to the CGA "snow" problem. If you have a CGA monitor and do not
-	suffer from snow, you can compile private\_queryad.c with CGA_DIRECT
-	defined. This will then use cause PDCurses to write directly to the
-	CGA video memory.
-
-	Function debugging: Firstly to get function debugging, you have to
-	compile the library with OPT=N in the makefile. This also turns on
-	compiler debugging. You can control when you want PDCurses to write
-	to the debug file (called trace in the current directory) by using
-	the functions traceon() and traceoff() in your program.
-
-	Microsoft C 6.00 Users note:
-	----------------------------
-	With the addition of several new functions, using dmake to compile 
-	PDCurses now causes the compiler to run "out of heap space in pass 2".
-	Using the 6.00AX version (DOS-Extended) to compile PDCurses fixes
-	this problem; hence the -EM switch.
-
-	Functional changes
-	------------------
-	A few curses functions have been fixed to exhibit their correct 
-	behaviour and make them more functionally portable with System V
-	curses.
-	The functions that have changed are overlay(), overwrite() and
-	typeahead.
-
-	overlay() and overwrite()
-	Both of theses functions in PDCurses 2.0 allowed for one window to
-	be effectively placed on top of another, and the characters in the
-	first window were overlayed or overwritten starting at 0,0 in both
-	windows. This behaviour of these functions was not correct. These
-	functions only operate on windows that physically overlap with
-	respect to the displayed screen. To achieve the same functionality
-	as before, use the new function copywin(). See the manual page for
-	further details.
-
-	typeahead()
-	This function in PDCurses 2.0 effectively checked to see if there
-	were any characters remaining in the keyboard buffer. This is not
-	the behaviour exhibited by System V curses. This function is intended
-	purely to set a flag so that curses can check while updating the
-	physical screen if any keyboard input is pending. To achieve the
-	same effect with typeahead() under PDCurses 2.1 the following code 
-	should be used.
-
-	In place of...
-
-		while(!typeahead(stdin))
-		 {
-			/* do something until any key is pressed... */
-		 }
-
-	use...
-
-		nodelay(stdscr,TRUE); /* getch() to return ERR if no key pending */
-		while(getch() == (ERR))
-		 {
-			/* do something until any key is pressed... */
-		 }

-
-PDCurses 2.0 - 1992/11/23
-=========================
-
-INTRODUCTION:
-
-	Well, here it finally is; PDCurses v2.0.
-	
-	PDCurses v2.0 is an almost total rewrite of PCCurses 1.4 done by John
-	'Frotz' Fa'atuai, the previous maintainer.
-	
-	This version has been tested with Microsoft C v6.0, QuickC v2.0 and
-	Borland C++ 2.0 under DOS and Microsoft C v6.0 and TopSpeed c v3.02
-	under OS/2 2.0. Also the library has been compiled successfully with
-	emx 0.8e, C Set/2 and Watcom 9.
-	Most testing was done with the large memory model where applicable.
-	The large memory model is probably the best model to use.
-	
-	The amount of testing has not been as extensive as I would have
-	liked, but demands on releasing a product have outweighed the
-	product's quality. Nothing new with that !!
-	Hopefully with wider circulation, more bugs will be fixed more quickly.
-	
-	I have included just 1 makefile which is suitable for dmake 3.8 for
-	both DOS and OS/2. The makefile does not rely on customisation of the
-	dmake.ini file.
-	
-	If you discover bugs, and especially if you have fixes, please let me
-	know ASAP.
-	
-	The source to the library is distributed as a zip file made with zip
-	1.9. You will need Info-ZIP unzip 5.0 to unzip.
-	Follow the directions below to compile the library.
-
-DIRECTIONS:
-
-	1.Create a new directory in which to unzip pdcurs20.zip. This will
-	  create a curses directory and a number of subdirectories containing
-	  source code for the library and utilities and the documentation.
-
-	2.Make changes to the makefile where necessary:
-	  Change the MODEL or model macro to the appropriate value (if it
-	  applies to your compiler). Use model for Borland compilers.
-
-	  Change any paths in the defined macros to be suitable for your
-	  compiler.
-
-	3.Invoke DMAKE [-e environment_options] [target]
-	
-	  where environment_options are:
-
-		OS (host operating system)
-		COMP (compiler)
-		OPT (optimised version or debug version) - optional. default Y
-		TOS (target operating system) - optional. default OS
-
-		see the makefile for valid combinations
-
-		targets: all, demos, lcursesd.lib, manual...
-		
-		NB. dmake is case sensitive with targets, so those environments
-		that use an upper case model value (eg MSC) MUST specify the
-		library target as for eg. Lcursesd.lib
-
-		The makefile is by default set up for Borland C++. The use of
-		-e environment_options override these defaults. Of you prefer
-		you can just change the defaults in the makefile and invoke it
-		without the -e switch.
-
-OTHER NOTES:
-
-	The documentation for the library is built into each source file,
-	a couple of specific doc files and the header files. A program is
-	supplied (manext) to build the manual. This program gets compiled
-	when you build the documentation.
-	
-	To generate the library response file correctly, I had to write a
-	quick and dirty program (buildlrf) to achive this. Originally the
-	makefiles just had statements like: "echo -+$(OBJ)\$* & >> $(LRF)"
-	which appended a suitable line to the response file. Unfortunately
-	under some combinations of makefiles and command processors (eg.
-	nmake and 4DOS) the & would get treated as stderr and the echo
-	command would fail.
-	
-	The original source for PDCurses that I received from the previous
-	maintainer contained support for the FLEXOS operating system. Not
-	having access to it, I could not test the changes I made so its
-	support has fallen by the wayside. If you really need to have PDCurses
-	running under FLEXOS, contact me and I will see what can be arranged.
-	
-	Under DOS, by default, screen writes to a CGA monitor are done via
-	the video BIOS rather than by direct video memory writes. This is
-	due to the CGA "snow" problem. If you have a CGA monitor and do not
-	suffer from snow, you can compile private\_queryad.c with CGA_DIRECT
-	defined. This will then use cause PDCurses to write directly to the
-	CGA video memory.
-
-COMPILER-SPECIFIC NOTES:
-
-	Microsoft C
-	-----------
-	It is possible with MSC 6.0 to build the OS/2 libraries and demo
-	programs from within DOS. This is the only case where it is possible
-	to specifiy the value of TOS on the command line to be OS2 and the
-	value of OS be DOS.
-
-	C Set/2
-	-------
-	I have only tested the library using the migration libraries. I doubt
-	that the demo programs will work without them.
-
-	emx
-	---
-	Testing has been done with 0.8e of emx together with the 16_to_32
-	libraries.
-	The emx\lib directory should include the vio32.lib and kbd32.lib
-	libraries from the 16_to_32 package.
-
-BUGS and UNFINISHED BUSINESS:
-
-	PDC_set_ctrl_break() function does not work under OS/2.
-	win_print() and PDC_print() do not work under OS/2.
-	The file todo.man in the doc directory also lists those functions of
-	System V 3.2 curses not yet implemented. Any volunteers ?
-
-ACKNOWLEGEMENTS:
-
-	John 'Frotz' Fa'atuai, the previous maintainer for providing an
-	excellent base for further development.
-	John Burnell (johnb@kea.am.dsir.govt.nz), for the OS/2 port.
-	John Steele, Jason (finally NOT a John) Shumate....
-	for various fixes and suggestions.
-	Eberhardt Mattes (author of emx) for allowing code based on his
-	C library to be included with PDCurses.
-	Several others for their support, moral and actual.

-PCCURSES 1.4 - 1990/01/14
-=========================
-
-  This is the release note for the fifth version of PCcurses, v.1.4.
-Below this note, the release notes for v.1.0 - v.1.3 are included. Read
-those first.
-
-  In PCcurses v.1.4, both portability improvements and bugfixes have
-been made. The files have been changed to allow lint-free compilation
-with MicroSoft 'C' v.5.1, and with Turbo 'C' v.2.0. The source should
-still compile without problems on older compilers, although this has
-not been verified.
-
-  The makefiles have been changed to suit both the public release and
-the author, who maintains a special kind of libraries for himself. In
-the case of MicroSoft 'C', changes were done in the makefile to lower
-the warning level to 2 (was 3). This was to avoid ANSI warnings which
-are abundant because PCcurses does not attempt to follow strict ANSI
-'C' standard.
-
-  BUG FIXES FROM V.1.3 TO V.1.4:
-
-  !!!IMPORTANT CHANGE!!!
-
-  The definitions for OK and ERR in curses.h were exchanged. This was
-done to be more consistent with UNIX versions. Also, it permits func-
-tions like newwin() and subwin() to return 0 (=NULL) when they fail
-due to memory shortage. This incompatibility with UNIX curses was
-pointed out by Fred C. Smith. If you have tested success/failure by
-comparisons to anything other than ERR and OK, your applications will
-need to be be changed on that point. Sorry... but presumably most of
-you used the symbolic constants?
-
-  (END OF IMPORTANT CHANGE)
-
-  Fred also pointed out a bug in the file update.c. The bug caused the
-first character printed after 'unauthorized' screen changes (like du-
-ring a shell escape, for example) to be placed at the wrong screen posi-
-tion. This happened even if the normal precautions (clear / touch / re-
-fresh) were taken. The problem has now been fixed.
-
-  PCcurses is currently also being used on a 68000 system with hard-
-coded ESCape sequences for ANSI terminals. However, int's used by the
-68000 C compiler are 32 bits. Therefore int's have been turned into
-short's wherever possible in the code (otherwise all window structures
-occupy twice as much space as required on the 68000). This does not
-affect PC versions since normally both int's and short's are 16 bits
-for PC C compilers.
-
-  At some places in the source code there are references made to the
-68000 version. There are also a makefile, a curses68.c file, and a
-curses68.cmd file. These are for making, low-level I/O, and linking
-commands when building the 68000 version. These files are probably
-useful to no-one but the author, since it is very specific for it's
-special hardware environment. Still in an effort to keep all curses-
-related sources in one place they are included. Note however that
-PCcurses will not officially support a non-PC environment.
-
-  The file cursesio.c, which was included in the package at revision
-level 1.2, and which was to be an alternative to the cursesio.asm
-file, has been verified to behave incorrectly in the function
-_curseskeytst(). The problem was that the value of 'cflag' does not
-contain the proper data for the test that is attempted. Furthermore,
-neither Turbo'C' or MicroSoft'C' allows any way to return the data
-that is needed, and consequently you should not use cursesio.c. The
-best solution is to simply use the ASM version. In v.1.2 and v.1.3,
-the user could edit the makefile to select which version he wanted to
-use. The makefiles in v.1.4 have removed this possiblity forcing the
-use of the ASM file, and cursesio.c has been dropped from the distri-
-bution.
-
-  A bug in the wgetstr() function caused PCcurses to echo characters
-when reading a keyboard string, even if the echo had been turned off.
-Thanks to Per Foreby at Lund University, Sweden, for this. Per also
-reported bugs concerning the handling of characters with bit 8 set.
-Their ASCII code were considered as lower than 32, so they were
-erased etc. like control characters, i.e. erasing two character posi-
-tions. The control character test was changed to cope with this.
-
-  The overlay() and overwrite() functions were changed so that the
-overlaying window is positioned at it's 'own' coordinates inside the
-underlying window (it used to be at the underlying window's [0,0]
-position). There is some controversy about this - the documentation
-for different curses versions say different things. I think the
-choice made is the most reasonable.
-
-  The border() and wborder() functions were changed to actually draw
-a border, since this seems to be the correct behaviour of these func-
-tions. They used to just set the border characters to be used by
-box(). These functions are  not present in standard BSD UNIX curses.
-
-  The subwin() function previously did not allow the subwindow to be
-as big as the original window in which it was created. This has now
-been fixed. There was also the problem that the default size (set by
-specifying numlines or numcols (or both) as 0 made the resulting
-actual size 1 line/column too small.
-
-  There were a few spelling errors in function names, both in the
-function declarations and in curses.h. This was reported by Carlos
-Amaral at INESC in Portugal. Thanks! There was also an unnecessary
-(but harmless) parameter in a function call at one place.

-PCCURSES 1.3 - 1988/10/05
-=========================
-
-  This is the release note for the fourth version of PCcurses, v.1.3.
-Below this note, the release notes for v.1.0, v.1.1 and v.1.2 are in-
-cluded. Read those first.
-
-  The file 'border.c' is now included. It allows you to explicitely speci-
-fy what characters should be used as box borders when the box() functions
-are called. If the new border characters are non-0, they override the bor-
-der characters specified in the box() call. In my understanding, this func-
-tionality is required for AT&T UNIX sV.3 compatibility. Thanks for this
-goes to Tony L. Hansen (hansen@pegasus.UUCP) for posting an article about
-it on UseNet (newsgroup comp.unix.questions; his posting was not related
-at all to PCcurses).
-
-  The only other difference between v.1.2 and v.1.3 is that the latter has
-been changed to avoid warning diagnostics if the source files are compiled
-with warning switches on (for MicroSoft this means '-W3', for Turbo'C' it
-means '-w -w-pro'). Of these, the Turbo'C' warning check is clearly to be
-used rather than MicroSoft, even if neither of them comes even close to a
-real UNIX 'lint'. Some of the warnings in fact indicated real bugs, mostly
-functions that did not return correct return values or types.
-
-  The makefiles for both MSC and TRC have been modified to produce warning
-messages as part of normal compilation.
-
-------------------------------------------------------------------------
-
-PCCURSES 1.2 - 1988/10/02
-=========================
-
-  This is the release note for the third version of PCcurses, v.1.2.
-Below this note, the release notes for v.1.0 and v.1.1 are included. Read
-those first.
-
-  The changes from v.1.1 to v.1.2 are minor. The biggest change is that there
-was a bug related to limiting the cursor movement if the application tried to
-move it outside the screen (something that should not be done anyway). Such
-erronous application behaviour is now handled appropriately.
-
-  All modules have been changed to have a revison string in them, which makes
-it easier to determine what version is linked into a program (or what library
-version you have).
-
-  There is now a 'cursesio.c' file. That file does the same as 'cursesio.asm'
-(i.e. it provides the interface to the lower-level system I/O routines). It
-is written in 'C' and thus it is (possibly) more portable than the assembler
-version (but still not so portable since it uses 8086 INT XX calls directly).
-When one creates new curses libraries, one chooses whether to use the assem-
-bler or the 'C' version of cursesio. The choice is made by commenting out the
-appropriate dependencies for cursesio.obj, near the end of the makefiles.
-
-  There is now a 'setmode.c' file. That file contains functions that save and
-restore terminal modes. They do it into other variables than do savetty() and
-resetty(), so one should probably use either savetty()/resetty() or the new
-functions only - and not mix the both ways unless one really knows what one
-does.
-
-  Diff lists vs v.1.0 are no longer included in the distribution. The make
-utility still is. PCcurses v.1.2 still compiles with MicroSoft 'C' v.4.0,
-and with Borland Turbo 'C' v.1.0. There is as far as I know no reason to be-
-lieve that it does not compile under MicroSoft 'C' v.3.0 and 5.x, or Turbo-
-'C' v.1.5, but this has not been tested.
-
-  There are two makefile's included, one for MicroSoft 'C', one for Turbo-'C'.
-They are both copies of my personal makefile's, and as such they reflect the
-directory structure on my own computer. This will have to be changed before
-you run make. Check $(INCDIR) and $(LIBDIR) in particular, and make the choice
-of ASM or 'C' cursesio version as mentioned above (the distribution version
-uses the 'C version of cursesio).
-
-  The manual file (curses.man) has been changed at appropriate places.
-
-  I would like to thank the following persons for their help:
-
-  	Brandon S. Allbery (alberry@ncoast.UUCP)
-		for running comp.binaries.ibm.pc (at that time)
-		and comp.source.misc.
-
-	Steve Balogh (Steve@cit5.cit.oz.AU)
-  		for writing a set of manual pages and posting
-		them to the net.
-
-	Torbjorn Lindh
-		for finding bugs and suggesting raw
-		character output routines.
-
-	Nathan Glasser (nathan@eddie.mit.edu)
-  		for finding and reporting bugs.
-
-	Ingvar Olafsson (...enea!hafro!ingvar)
-  		for finding and reporting bugs.
-
-	Eric Rosco (...enea!ipmoea!ericr)
-  		for finding and reporting bugs.
-
-	Steve Creps (creps@silver.bacs.indiana.edu)
-  		for doing a lot of work - among others
-		posting bug fixes to the net, and writing
-		the new cursesio.c module.
-
-	N. Dean Pentcheff (dean@violet.berkeley.edu)
-  		for finding bugs and rewriting cursesio.asm
-		for Turbo 'C' 1.5.
-
-  Finally, Jeff Dean (parcvax,hplabs}!cdp!jeff)
-  		     (jeff@ads.arpa)
-	has had a shareware version of curses deliverable since
-	about half a year before I released PCcurses 1.0 on Use-
-	Net. He is very concerned about confusion between the two
-	packages, and therefore any references on the network
-	should make clear whether they reference Dean's PCcurses
-	or Larsson's PCcurses.

-PCCURSES 1.1 - 1988/03/06
-=========================
-
-  This is the release note for the second version of PCcurses, v.1.1.
-Below this note, the release note for v.1.0 is included. Read that first.
-The changes from v.1.0 to v.1.1 are minor. There are a few bug fixes, and
-new (non-portable) functions for verbatim IBM character font display have
-been added (in charadd.c and charins.c). The manual file (curses.man) has
-been changed at appropriate places.
-
-  In the file v10tov11.dif there are listings of the differencies between
-version 1.0 and 1.1. The diff listings are in UNIX diff(1) format.
-
-  Version 1.1 compiles with Turbo 'C' v.1.0, as well as MicroSoft 'C' v.3.0
-and v.4.0. On the release disk there is a make.exe utility which is very simi-
-lar to UNIX make (If the package was mailed to you, the make utility will be
-in uuencoded format - in make.uu - and must be uudecoded first). It is much
-more powerful than MicroSoft's different MAKE'S; the latter ones will NOT ge-
-nerate libraries properly if used with the PCcurses makefiles.
-
-  There are three makefiles:
-
-	makefile		generic MSC 3.0 makefile
-	makefile.ms		MSC 4.0 makefile
-	makefile.tc		Turbo 'C' 1.0 makefile
-
-  To make a library with for example Turbo 'C', make directories to hold .H
-and .LIB files (these directories are the 'standard places'), edit makefile.tc
-for this, and type
-
-	make -f makefile.tc all
-
-and libraries for all memory models will be created in the .LIB directory,
-while the include files will end up in the .H directory. Also read what is
-said about installation below!

-
-PCCURSES 1.0 - 1987/08/24
-=========================
-
-  This is the release notes for the PCcurses v.1.0 cursor/window control
-package. PCcurses offers the functionality of UNIX curses, plus some
-extras. Normally it should be possible to port curses-based programs from
-UNIX curses to PCcurses on the IBM PC without changes. PCcurses is a port/
-rewrite of Pavel Curtis' public domain 'ncurses' package. All the code has
-been re-written - it is not just an edit of ncurses (or UNIX curses). I
-mention this to clarify any copyright violation claims. The data struc-
-tures and ideas are very similar to ncurses. As for UNIX curses, I have
-not even seen any sources for it.
-
- For an introduction to the use of 'curses' and it's derivatives, you
-should read 'Screen Updating and Cursor Movement Optimization: A Library
-Package' by Kenneth C. R. C. Arnold, which describes the original Berkely
-UNIX version of curses. It is available as part of the UNIX manuals. The
-other source of information is 'The Ncurses Reference Manual' by Pavel
-Curtis. The latter is part of Curtis' ncurses package.
-
-  The only other documentation provided is a 'man' page which describes
-all the included functions in a very terse way. In the sources, each
-function is preceded by a rather thourough description of what the
-function does. I didn't have time to write a nice manual/tutorial - sorry.
-
-  PCcurses is released as a number of source files, a man page, and a make
-file. A uuencoded copy of a 'make' utility, and a manpage for the 'make' is
-also provided to make it easier to put together PCcurses libraries. Even if
-you are not interested in PCcurses, it may be worthwhile to grab the make.
-
-  The makefile assumes the presence of the MicroSoft 'C' compiler (3.0 or
-4.0), MicroSoft MASM and LIB, plus some MS-DOS utilities. The reason for
-supplying MAKE.EXE is that the MicroSoft 'MAKE:s' are much inferior to a
-real UNIX make. The supplied make is a port of a public domain make, pub-
-lished on UseNet. It is almost completely compatible with UNIX make. When
-generating the curses libraries, the makefile will direct make to do some
-directory creating and file copying, and then re-invoke itself with new
-targets. The workings of the makefile are not absolutely crystal clear at
-first sight... just start it and see what it does.
-
-  For portability, the curses libraries depend on one assembler file for
-access to the BIOS routines. There is no support for the EGA, but both
-CGA, MGA, and the HGA can be used. The libraries are originally for Micro-
-Soft 'C', but all C modules should be portable right away. In the assembler
-file, segment names probably need to be changed, and possibly the parameter
-passing scheme. I think Turbo C will work right away - as far as I under-
-stand, all it's conventions are compatible with MicroSoft C.
-
-  There are some parts left out between ncurses and PCcurses. One is the
-support for multiple terminals - not very interesting on a PC anyway. Be-
-cause we KNOW what terminal we have, there is no need for a termcap or
-termio library. PCcurses also has some things that neither curses nor
-ncurses have. Compared to the original UNIX curses, PCcurses has lots
-of extras.
-
-  The BIOS routines are used directly, which gives fast screen updates.
-PCcurses does not do direct writes to screen RAM - in my opinion it is
-a bit ugly to rely that much on hardware compatibility. Anyone could fix
-that, of course...
-
-  One of the more serious problems with PCcurses is the way in which nor-
-mal, cbreak, and raw input modes are done. All those details are in the
-'charget' module - I do raw I/O via the BIOS, and perform any buffering
-myself. If an application program uses PCcurses, it should do ALL it's
-I/O via PCcurses calls, otherwise the mix of normal and PCcurses I/O may
-mess up the display. I think my code is reasonable... comments are welcome,
-provided you express them nicely...
-
-  To install, copy all files to a work directory, edit 'makefile' to define
-the standard include and library file directory names of your choice (these
-directories must exist already, and their path names must be relative to the
-root directory, not to the current one). You must also run uudecode on
-make.uu, to generate MAKE.EXE. You can do that on your PC, if you have
-uudecode there, otherwise you can do it under UNIX and do a binary transfer
-to the PC. When you have MAKE.EXE in your work directory (or in your /bin
-directory), type make.
-
-  Make will now create 4 sub-directories (one for each memory model), copy
-some assembler include files into them, copy two include files to your
-include directory, CHDIR to each sub-directory and re-invoke itself with
-other make targets to compile and assemble all the source files into the
-appropriate directories. Then the library manager is run to create the
-library files in your desired library directory. Presto!
-
-  If you only want to generate a library for one memory model, type 'make
-small', 'make large', etc. The name of the memory model must be in lower
-case, like in the makefile.
-
-  I think the package is fairly well debugged - but then again, that's
-what I always think. It was completed in May-87, and no problems found
-yet. Now it's your turn... Comments, suggestions and bug reports and
-fixes (no flames please) to
-
