parcimonie 0.12.0 Incrementally refreshes a GnuPG keyring

Parcimonie incrementaly refreshes a GnuPG keyring in a way that makes it hard to correlate the keyring content to an individual, and makes it hard to locate an individual based on an identifying subset of her keyring content. Parcimonie is a daemon that fetches one key at a time using the Tor network, waits a bit, changes the Tor circuit being used, and starts over.
