I still use it. I think it differs in many ways from the original version (the Caldera licence was to allow the 7th Edition code to be used in 2002).

Not least that it's formatted and arranged to be readable. It made some things dynamic so it could handle large reference libraries.

There were bug fixes.

I also replaced the original's internal fgrep implementation by the Aho-Corasick as developed in the paper.
