* test/: Makefile.am, check_nrg.sh, check_nrg.sh.in: check_nrg.sh
is now derived since we may or may not have Video CD info
displayed.
2003-04-26 10:24 rocky
* configure.ac, src/Makefile.am, src/cd-info.c, test/cdda.right,
test/check_cue.sh.in, test/check_nrg.sh, test/check_opts0.right,
test/check_opts1.right, test/check_opts4.right,
test/check_opts5.right, test/check_opts6.right,
test/check_opts7.right, test/isofs-m1.right, test/monvoisin.right,
test/svcd_ogt_test_ntsc.right, test/svcdgs.right,
test/vcd_demo.right, test/videocd.right: cd-info: Use libvcdinfo if
it is around to list out general Video CD properties (format
version, album description, preparer id, volume number and count).
cd-info output changed slightly.

* ChangeLog, Makefile.am, src/Makefile.am, src/cd-info.c,

programs. Thanks to Manfred Tremmel <Manfred.Tremmel@iiv.de> for
reporting the problem.
