Subject: string to (valid) filename

Don't know much about regexes or File/FileUtils, and am a bit stuck on what
might be quite simple:

Is there a simple way to create a valid filename (develop on XP, but would
like the filenames to be valid at least on *nix as well) from a string that
might contain several platform-illegal filename characters. The conversion
could change spaces etc. to '_'.

e.g.
"Animals: Fox, Wolf, and Bear".to_filename
#=> "animals_fox_wolf_and_bear"

Thanks
