This is the new and improved, canonical sogrep command, now with a valid
license.
The previous version of sogrep had several issues and inefficiencies,
and ultimately wasn't really the finished project I wanted it to be. Due
to a mistake in communication, I was totally unaware it was in the
process of being merged at all, nor that there was a licensing issue, or
I would have recommended waiting for both further improvements, and a
declaration of license intent; nevertheless, here it is now, and I
formally give this over into the GPLv2+ domain.
