This will definitely be useful for helping switch between work and personal projects on the same laptop!

A more generic tool for this type of function is direnv[http://direnv.net/].

I use direnv for example for setting per-directory Perl installation variables to keep my development environments separate.

From my (admittedly brief) glance at the documentation, this seems like the opposite of direnv. direnv would allow you to set up configuration values on a per-directory basis, by adding a file in the directory in question. git supports this already, you can simply change the config for the repository in question. The goal of this package appears to automate this so that one doesn't need to reconfigure each individual folder.

Does this handle management of SSH keys?

I already do this with a simple shell script:

  if [ $1 == "home" ]; then
        ssh-add -D
        ssh-add ~/.ssh/id_rsa_home
        ssh -T git@github-home
        exit;
  fi

where in ~/.ssh/config:

  Host github-home
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_rsa_home
    IdentitiesOnly yes

I was hoping that as well, that's the main challenge with multiple identities, but it seems it's not included on karn :(

I also have stuff like this lying around. Please don't tell Github because I seem to remember it is against their policy.

Actually they're okay with it. I checked with them about how to do this and they recommended a single account instead. When I said I needed to keep my corporate and personal accounts separate for policy reasons, they were fine with it.
