Tux Machines (TM)-specific
One of the things that I love about Linux is that it has tools for everyone, including writers. Linux distributions come with word processors, text editors, spell checkers, typesetting, and publishing tools galore. Normally, you're using these tools with a standard desktop distribution in an environment like KDE or GNOME. Billy-Bob Ming, however, has taken a different tack and rolled his own Linux distro specifically aimed at writers.
GhostWriter is a live CD that provides a small number of tools for writers of short stories, novels, and screenplays. But GhostWriter can be used by someone authoring works of non-fiction as well. It's easy to use and has a small footprint. In fact, there's nothing to install -- you run GhostWriter off a CD. Unlike some live CD distros, GhostWriter doesn't have install scripts that let you make it a desktop distribution, but Ming has hinted that a future version might come with such scripts.
GhostWriter is a novel approach to writing and publishing documents -- perhaps a little too novel for many writers.
