+ *
+ * Revision 1.7 2001/06/29 13:33:04 oes
+ * - Cleaned up, renamed and reordered functions,
+ * improved comments
+ * - Removed my_strsep
+ * - Replaced globalflag with a general flags int
+ * that holds PCRS_GLOBAL, PCRS_SUCCESS, and PCRS_TRIVIAL
+ * - Introduced trivial option that will prevent pcrs
+ * from honouring backreferences in the substitute,
+ * which is useful for large substitutes that are
+ * red in from somewhere and saves the pain of escaping
+ * the backrefs
+ * - Introduced convenience function pcrs_free_joblist()
+ * - Split pcrs_make_job() into pcrs_compile(), which still
+ * takes a complete s/// comand as argument and parses it,
+ * and a new function pcrs_make_job, which takes the
+ * three separate components. This should make for a
+ * much friendlier frontend.
+ * - Removed create_pcrs_job() which was useless
+ * - Fixed a bug in pcrs_execute
+ * - Success flag is now handled by pcrs instead of user
