Speaking of regexp there are are two nice programs which allows you to
interactively check them (sort of like a spellcheck): regexplorer and
visual-regexp. The latter even has a "Make regexp" function that allows
you to "compute" a regexp from a given word list. The results aren't
always as elegant as can be. But they do give you a hint, especially if
you're new at ,say, procmail rules writing.
