> I can just try it, but what is CDPATH for?

CDPATH is a list of directories for the 'cd' command. I have '.' and
"$HOME" in my CDPATH. So, when I type 'cd folder', then folder can
either be in the current dir or in $HOME and 'cd' will switch to
whatever is first in CDPATH. A bit dangerous, but I came to like it.

I still don't see why this affects dir parsing of coccinelle...
