g0tmi1k@kali-dev:~$ pdgmail -h
Usage: /usr/bin/pdgmail [OPTIONS]

Options:
   -f, --file       the file to use (stdin if no file given)
   -b, --bodies     don't look for message bodies (helpful if you're getting too many false positives on the mb regex)
   -h, --help       prints this 
   -v,--verbose     be verbose (prints filename, other junk)
   -V,--version     prints just the version info and exits.

This expects to be unleashed on the result of running strings -el on a pd dump from windows process memory. Anything other than that, your mileage will certainly vary.

Could /usr/bin/ be dropped?
