description         Perl compatibility regular expressions for OCaml
long_description    This OCaml-library interfaces the PCRE (Perl-compatibility regular \
                    expressions) library which is written in C. it can be used for matching \
                    regular expressions which are written in PERL-style. Searching for, replacing \
                    or splitting text should become much easier with this library.
