/*****
* ChangeLog
* $Log: fflow.l,v $
* Revision 1.9 1996/08/28 17:45:21 koen
* Added print_version_id; added the -llevel option and appropriate changes.
*
* Revision 1.8 1996/08/27 19:16:01 koen
* Heavy changes: updated scanner rules; optimized memory allocation routines;
* moved a number of routines to libflow.c
*
* Revision 1.7 1996/08/07 21:14:24 koen
* Updated for MSDOS and added warning messages when -I, -E or -x is exceeded
*
* Revision 1.6 1996/08/02 14:50:29 koen
* Added the -n and -n- options. Moved all system dependencies to lib/sysdeps.h
*
* Revision 1.5 1996/07/30 02:00:57 koen
* Changed output stuff.
* Added missing things to command line options.
* Added version information.
* Changed the ignore_this_file routine to use strstr.
* Fixed a bug which left files open when a file was to be ignored.
*
* Revision 1.4 1996/07/16 09:05:44 koen
* cmd_line related bug fixed.
* Changed all fprintf(stderr,...) to printf(...) where output on stdout is
* expected
*
* Revision 1.3 1996/05/06 00:34:40 koen
* Adapted for MSDOS.
*
* Revision 1.2 1996/02/05 01:45:29 koen
