Initial import

[[This repository was converted from Subversion to Git on 2014-01-22
by Mike Swanson <mikeonthecomputer@gmail.com>. Some commits have been
coalesced into a single commit and a handful of others junked
entirely. Tag commits have been squashed back to the master branch, so
hopefully operations like "git describe" work as intended. Except in
one special case, revision references have been replaced by the
VCS-independent action stamp syntax that should remain constant no
matter the underlying VCS used.]]
