regular expression library for OCaml

 RE is regular expression library for OCaml. The following styles of
 regular expressions are supported:
  * Perl-style regular expressions (module Re.Perl);
  * Posix extended regular expressions (module Re.Posix);
  * Emacs-style regular expressions (module Re.Emacs);
  * Shell-style file globbing (module Re.Glob);
  * Compatibility layer for OCaml's built-in Str module (module Re.Str).
 .
 It is also possible to build regular expressions by combining simpler
 regular expressions (module Re)
 .
 This package contains the development modules you need to use RE in
 your programs.
