If there's ever a bit of idiom that you *almost* know, but can't quite nail, and you're too shy to ask on the chatterbox,

I stretched my arm out and got "Programming Perl" from my Perl book pile. (The only problem here is the sheer size of the index, which adds seconds of page turning.) Also, "perldoc -f mkdir" worked fine for me.

But I'd have missed the "File::Path" comment here. Hmmm... the Chatterbox seems to be the best place, all things considered.
