# This is the version string used when it isn't possible to do a git describe,
# which happens with a git-archive tarball for instance. A '+' is appended to
# the version string to mean that it's a development version eg. 3.0.0+ means
# somewhere between 3.0.0 and 3.0.1.
#
# The version should be bumped and the '+' sign removed just before tagging a
# new release.
# A '+' sign should be added in the commit just after tagging a new release.
