Extra info and code examples

After a key-signing party, pius (the PGP Individual UID Signer) signs each uid on a GPG key individually. Each signature is encrypted and mailed to the email address associated with that particular uid. As a result of this process, the recipient can choose which signatures to import. Also, signatures of inactive uids are not delivered. This tool greatly reduces time and error when signing keys. Other tools herein are useful for organizers: pius-keyring-mgr builds a party keyring from a CSV file or by scanning mailboxes, and pius-party-worksheet generates a worksheet as a hand out. If someone has not signed your key, pius-report can analyze a party keyring and remind them. This version supports GPGv2 and uses it by default.
