$(basename ${BASH_SOURCE}) [--help] [-k KEY_ID] [-m] DIST_COMMIT_HASH
Create a source distribution archive, signature file, release notes, and

-h,--help
Print this usage text and exit.

Specify a GPG private key ID (like 0xABCEDF), which will be used to sign

used.
-m,--manifest
Create a plaintext manifest file of all members in the dist archive.
(Useful for comparing with previous releases.)
