Git tools used when working with the opensourceradio repos.

As of now, this repo contains only my versions of tools snagged from other places on the interwebs. See, e.g., http://stackoverflow.com/questions/384108/moving-from-cvs-to-git-id-equivalent and http://stackoverflow.com/questions/16524225/how-can-i-populate-the-git-commit-id-into-a-file-when-i-commit for references.

1. A pair of scripts to manipulate the source files

• add-hash is a ruby script that's used to grab the current commit hash on checkout and insert it into any file that includes the string $Hash$

• clean-hash is a perl script that removes all commit hashes from strings in any file on commit.

  These scripts should be in your ${PATH}.

1. Your git configuration (system, user, or local) must include the following in order to use these scripts:

git config --add filter.buildsub.clean clean-hash
git config --add filter.buildsub.smudge add-hash

1. Your local repo must include a .gitattributes file containing:

* filter=buildsub

Note that the filter name is arbitrary: the filter name in the two configuration settings, and the filter setting in .gitattributes must match.
