31 * Revision 1.4 1998/11/13 03:37:01 tridge
32 * fixes for OSF1 compilation
34 * Revision 1.3 1998/10/28 20:33:35 crh
35 * I've moved the debugparse module files into the ubiqx directory because I
36 * know that 'make proto' will ignore them there. The debugparse.h header
37 * file is included in includes.h, and includes.h is included in debugparse.c,
38 * so all of the pieces "see" each other. I've compiled and tested this,
39 * and it does seem to work. It's the same compromise model I used when
40 * adding the ubiqx modules into the system, which is why I put it all into
41 * the same directory.

45 * Revision 1.1 1998/10/26 23:21:37 crh
46 * Here is the simple debug parser and the debug2html converter. Still to do:
48 * * Debug message filtering.
49 * * I need to add all this to Makefile.in
50 * (If it looks at all strange I'll ask for help.)
52 * If you want to compile debug2html, you'll need to do it by hand until I
53 * make the changes to Makefile.in. Sorry.
