"""find-decrypted [<options>] [<dir> [<dir> ...]]

Looks for forgotten decrypted files in the given directories.  This script can
be run to insure that there are not decrypted files left in a directory where
there are encrypted files.  Output is the name of the files that are decrypted
and that probably should not be there.

I typically use this on my doubly encrypted files: my emacs setup can read and
write encrypted files without backups, but not for doubly-encrypted files.
Sometimes I forget decrypted files in those directories.  Not a good thing.
