# One command, run on the machine that will host your app, from the app's
# directory. When grund is released it will install grund on this machine and
# put the app in this directory live at the domain you give it.
#
# grund is in development. Until it is released this script only says so and
# exits. It downloads nothing, writes nothing and changes nothing on this
# machine. Read it first, as you should with any script you pipe into sh.
#
# Everything runs inside main(), called on the last line, so a download cut
# short can never run half a script.
