These are my dotfiles. Setup is done by symbolic links, either manually or via Make. Repo is a work in progress.
The script gitdir.sh depends on an environment variable GITDIR. This variable can be set via the gitdir make recipe, or manually in ~/.env.
The enclosed .gitconfig-base is not automatically detected by Git, and has to be referenced in your actual .gitconfig to have any effect, like so:
[include]
path = ~/.gitconfig-base
This section should be put at the very top of the .gitconfig, so that all values below overwrite the baseline settings in .gitconfig-base.
