# Create source tarball from sdl-jstest git repo, with generated version
# number. Since the build expects to have the git log available (for
# embedding the git hash in --version output), don't rm -rf .git,
# but do use --depth 1 when cloning.

# Note that this script doesn't need to be run as root. It does need to
# be able to write to the current directory it's run from.

# Takes one optional argument, which is the commit or tag to create a
# tarball of. With no arg, HEAD is used.
