These are jpgrayson's dot files. They are meant to be portable to Linux and Mac OS X.
The install.py script cautiously creates symlinks from the repo to
$HOME. Example usage:
$ git clone https://github.com/jpgrayson/dot-files.git
$ cd dot-files
$ ./install.py
For already existing dot files, they will only be replaced by symlinks if their contents are identical to the corresponding dot file in the repo.
For existing dot directories, install.py asks whether to replace the
existing dot directory with a symlink to the repo.
