Usage: install [-s KERNEL] [-m ARCH] [-d DIR] [-f|-n] [-- CMD [ARG]...]
If positional arguments are specified, call this on success:
CMD [ARG]... DAEMON VERSION INSTALLED
DAEMON is path to gitstatusd. VERSION is a glob pattern for the
version this daemon should support; it's supposed to be passed as
-G to gitstatusd. INSTALLED is 1 if gitstatusd has just been
downloaded and 0 otherwise.
Options:
-s KERNEL use this instead of lowercase `uname -s`
-m ARCH use this instead of lowercase `uname -m`
-d DIR use this instead of `dirname "$0"`
-f download gitstatusd even if there is one locally
-n do not download gitstatusd (fail instead)
