Configure git email and signing key on a per-repository basis
#!/bin/sh -u
# Install this into ~/.githooks/pre-commit
#
# Make it executable:
# > chmod +x ~/.githooks/pre-commit
#
# Configure git to point at your hooks directory
# > git config --global core.hooksPath ~/.githooks
#
# ## Remove your signingkey from global git config
# > git config --global --unset user.signingkey
#
# ## Tell git to sign commits
# > git config --global gpg.program gpg2
# > git config --global commit.gpgsign true
#
# ## Tell Github about your email address
# https://github.com/settings/emails
#
# ## Tell Github about your OpenPGP key:
# > gpg --armor --export '<key fingerprint>'
#
# Then copy-paste to here:
# https://github.com/settings/keys
