Revision: 912
Committed: Wed Nov 7 22:47:44 2007 UTC (16 years, 4 months ago) by michael
File size: 6193 byte(s)
Log Message:
- Implemented libtool-ltdl. Only shared modules are supported currently
- Several build fixes and cleanups. ircd now builds and runs without any problems
- Added back all files to SVN that are needed to built the daemon
  I really don't want to force other people that want to test the snapshots
  or svn versions to install yyacc, lex, automake, autoconf and libtool...
  No problem having required files in svn
- Removed some automake maintainer stuff which is kinda useless for us

46 Usage: ylwrap [--help|--version] INPUT [OUTPUT DESIRED]... -- PROGRAM [ARGS]...
47
48 Wrapper for lex/yacc invocations, renaming files as desired.
49
50 INPUT is the input file
51 OUTPUT is one file PROG generates
52 DESIRED is the file we actually want instead of OUTPUT
53 PROGRAM is program to run
54 ARGS are passed to PROG
55
56 Any number of OUTPUT,DESIRED pairs may be used.
