A snapcraft recipe.

Forced to add description and summary because parse-info didn't work.
Used git source because snapcraft expects different directory layout.

+summary: Reference client for Bitmessage, a P2P communications protocol
+description: |
+  Bitmessage is a P2P communication protocol used to send encrypted messages to
+  another person or to many subscribers. It is decentralized and trustless,
+  meaning that you need-not inherently trust any entities like root certificate
+  authorities. It uses strong authentication, which means that the sender of a
+  message cannot be spoofed. BM aims to hide metadata from passive
+  eavesdroppers like those ongoing warrantless wiretapping programs. Hence
+  the sender and receiver of Bitmessages stay anonymous.
