This is a regular expression library for DM. Pretty much all of the standard Perl regex functionality is included, except some advanced features like look-ahead/behind assertions.
To work with this, just create the expression like so:
var/regex/R = new("/text/i")
usr << "Pattern match found: [copytext(R.match, R.index)]"
Full documentation is included.
