gpg signing extension for hg the principle is almost the same as how tags work: .hgsigs stores signatures, localsigs stores local signatures the format of the signatures is: nodeid sigversion base64_detached_sig sigversion 0 signs simply the nodeid (maybe we would like to sign other things in the future). you can associate fingerprints with roles in hgrc like: [gpg] fingerprint_of_a_key_without_spaces = release fingerprint_of_a_key_without_spaces = contributor, testing the key used for signing can be specified on the command line or via hgrc (key =) thanks to Eric Hopper for testing and bugfixing
