README.md

Some Git helper tools.

• githelper is a subcommand-based multi-purpose git tool and Python library, currently with a focus on git-svn working copies. It has its own documentation page
• git-checkout-by-date.sh lets you do exactly that
• git-working-copy-check.py performs some sanity checks on git working copies, recursively if requested
• template/hooks contains git hooks, for example a prepare-commit-msg hook to prepare informative merge commit messages
