# Script to use custom ssh keys for various git repositories
# Run without arguments to get usage info.
#
# How it works:
# When used with SSH, git sends the path to the repository in the SSH command.
#   @see: https://github.com/git/git/blob/e870325/connect.c#L1268
# We extract this info and search for a key with the name.
# Based on the source, this seems to be used format since v2.0 at least.

Powell's 6-Step Plan to NPM Happiness

When things go wrong:

1. Do what the error says.
2. rm -rf node_modules && npm install (if in Ember.js - rm -rf bower_components && bower install)
3. rm -rf node_modules && rm -rf ~/.npm && npm install
4. Reinstall node and npm.
5. Format your harddrive.
6. Buy a new computer.
