Shadowhand maintains a user repository, called Papercut, that contains beta and development versions of packages.

Note: Shadowhand used to maintain a second repository, called mousetrap, that contained a full Xfce built from Xfce's developer SVN repository. This has been moved into the official unstable repository.

Warning: This is a development-level user repository. Please read Development Repository#Warning

[edit] GONE!

Right now, all my stuff is in the unstable repository. This article is only around because I may add stuff to papercut again some day.

[edit] Papercut

Current packages include bmpx-svn and pympd-svn. Many of these packages have moved to unstable. To use this repository, add the following lines to your /etc/pacman.conf:

[papercut]
