Subject: Add new keys-from-userid subcommand to monkeysphere UI.
X-Git-Tag: monkeysphere_0.27~10
X-Git-Url: https://codewiz.org/gitweb?a=commitdiff_plain;h=fd03070ba488f9be9c479734bea9b0f741350221;p=monkeysphere.git

Add new keys-from-userid subcommand to monkeysphere UI.

This new subcommand calls a new function, keys_from_userid, that
outputs to stdout all acceptable keys for a given user ID literal.
