6 * File : $Source: /home/administrator/cvs/ijb/pcrs.h,v $
8 * Purpose : This is the pre-pre-alpha realease of libpcrs. It is only
9 * published at this (ugly) stage of development, because it is
10 * needed for a new feature in JunkBuster.
12 * Apart from the code being quite a mess, no inconsistencies,
13 * memory leaks or functional bugs **should** be present.
15 * While you ROTFL at the code, you could just as well mail me
16 * (oes@paradis.rhein.de) with advice for improvement.
18 * pcrs is a supplement to the brilliant pcre library by Philip
19 * Hazel (ph10@cam.ac.uk) and adds Perl-style substitution. That
20 * is, it mimics Perl's 's' operator.
22 * Currently, there's no documentation besides comments and the
25 * Copyright : Written and copyright 2001 by Sourceforge IJBSWA team.
29 * Revision 1.4 2001/05/11 01:57:02 rodney
30 * Added new file header standard w/RCS control tags.
32 * revision 1.3 2001/05/08 02:38:13 rodney
33 * Changed C++ "//" style comment to C style comments.
35 * revision 1.2 2001/04/30 02:39:24 rodney
36 * Made this pcrs.h file conditionally included.
38 * revision 1.1 2001/04/16 21:10:38 rodney
