Proposal: Use topkg for releases.

[rgrinberg]

Using topkg along with opam-publish to create releases. This has the following advantages:

• Automated process for making and submitting our own releases
• We'll be creating and uploading our own tarballs. Github sometimes likes to change the checksums of their archives. example
• Our releases will include the CHANGELOG from the previous release. example

I can set this up and add some small instructions for how to make a release using topkg.
