CL-PPCRE is a portable regular expression library for Common Lisp which has the following features:

• It is compatible with Perl.
• It is pretty fast.
• It is portable between ANSI-compliant Common Lisp implementations.
• It is thread-safe.
• In addition to specifying regular expressions as strings like in Perl you can also use S-expressions.
• It comes with a BSD-style license so you can basically do with it whatever you want.
