playground

Playground lets you try out .emacs.d configuration repositories.

The basic idea behind Playground is to create an isolated directory
called a sandbox and make it $HOME of Emacs.  Playground allows you
to easily experiment with various Emacs configuration repositories
available on GitHub, while keeping your current configuration
untouched (almost, except for stuffs related to Playground).
It can also simplify your workflow in Emacs by hiding irrelevant
files and directories existing in your home directory.
