-Then submit a pull request to homebrew-binary. Note that they're very, very careful about their
-commit history. If you made multiple commits, squash them. They don't merge using the button on
-GitHub, they merge by making sure that the branch is rebased on to the most recent master, and
-then they do a fast-forward merge. That means that the PR will be red when it's closed, not purple.
+Note that they really don't want any verbose commit messages or PR descriptions when all you're doing is bumping a version.
 
-Also, don't bother trying to DRY out the formula, they prefer having explicit, hard-coded values.
