A tool/system to manage dot files. Some ideas:

- easily install dot files on a new system

- keep track of files in git

- possible to specify different configurations (OS X, Linux, etc.)

- possible to exclude sensible dot files (i.e. .ssh/id_rsa)

- easy to update files and keep them in sync

- the tool should not be mixed with individual dot files repositories so that it's easy to upgrade to a newer version

- eventually: a dot file repository where people can share / show off their configurations

There are a few tools available on Github but none which have all the above features (AFAIK).
