make_links.sh

#!/usr/bin/env bash
# symlinks the dotfiles in this repository to their system location and backs
# them up if they already exist. If update-git is given as an argument, the
# system dotfilse are copied to the git repository instead. If the first
# argument is check, the integrity of the links (whether they exist and point to
# the right file) is checked.
#
# The script works with:
# 1. files that are copied directly into the home directory
# 2. directories that are copied directly into the home directory
# 3. files or directories that are copied into a subdirectory of ~ (keep in mind
#    that the first part of the path still is going to be prefixed with a dot.
