 liblightgrep is a library for searching data using regular expressions as
 defined in Unicode Technical Standard #18. There are lots of details,
 including a handy cheat sheet, at the project's homepage,
 http://www.lightboxtechnologies.com/lightgrep-engine.

 I am willing to be the maintainer of this port.
