What does regexp mean?

I found it in a help file mentioning various command line options in a program.Options:
--window <regexp>

It doesn't explain what a regular expression is. Nor does 'man regexp.'

I'm sorry as I don't know how to explain it either.

Perhaps these G4L search results for 'regexp regular expression' (http://www.google.com/linux?hl=en&lr=&ie=ISO-8859-1&q=regexp+regular+expression&btnG=Google+Search) will help at least until someone a bit more knowledgeable can reply.

First three results of this google search (http://www.google.com/search?q=regular%20expression%20definition&sourceid=mozilla-search&start=0&start=0&ie=utf-8&oe=utf-8) explains it pretty well I think:

Sadly, I used to be very good at these way back when studying comp. sci. at university. I suppose now's a good time as any to dust off 'ye old textbook charred remains' and see what's still legible....
