-To compile the source:
+0. To compile the source, you'll need a POSIX shell and utilites (sh,
+sed, grep, cat), an ANSI C compiler like gcc, and a POSIX "make"
+program like GNU make. You may also want to have "libtool" installed
+for building portable shared libraries.
+
+1. Uncompress and unpack the source code using for example "tar". Recent
+versions of GNU tar can do this in one step like this:
+  tar -xpf libcdio-*.bz  # or libcdio-*.gz
+
+2. Go into the directory, run "configure" followed by "make":
+
+  cd libcdio-*
+  sh ./configure MAKE=gmake 
+
+3. If step 2 works, Now compile everything:
 
-  ./configure MAKE=gmake 
   make
+
+4. Run the regression tests if you want:
+
   make check
-  make install  # may have to do this as root 
+
+5. Install. If the preceeding steps were successful:
+
+  make install  # you may have to do this as root 
+                # or "sudo make install"

 Of late FreeBSD folks have been pretty good about testing new releases
