gpg2openpgpkey.py version 0.1
Usage: gpg2openpgpkey.py [-g] [-h] <email> <gpgkeyfile>

       -g       Output DNS generic RDATA format (rather than OPENPGPKEY)
       -d DIR   Use DIR as base directory (default: /tmp/openpgpkey
       -c       Create and cleanup base directory as needed
       -h       Print this help message

Given an email address and a file containing a GPG public key, this program
generates a corresponding DNS OPENPGPKEY resource record in presentation
format.

This program uses /tmp/openpgpkey as the base directory for the temporary GPG
keyring files it generates. Make sure this directory exists and is writable
by the invoker. Or use the "-c" option to have the directory automatically
created and deleted.
