If you are committing for the first time, add your pgp public key to the gitian-pubkeys directory in armored ASCII format and a filename of `username.asc`.
## Verifying Gitian Signatures
The `verify-merge.py` script can be used to verify existing gitian sigs. For example to verify all the signatures on the v0.14.1.0 assert files, run `./verify-merge.py v0.14.1.0`. More information on how to use the script can be found by running `./verify-merge.py --help`.
It is also possible to use the script to check the signatures of open pull requests. For example for pull request id 12 on github: `./verify-merge.py --pull_id 12 v0.14.1.0`. Be aware that running this will change the content of your git tree by creating a new `$pull_id_head` and `$pull_id_base` branch. The script deletes these branches again on exit.
