# Usage: scoop install <app> [options]
# Summary: Install apps
# Help: e.g. The usual way to install an app (uses your local 'buckets'):
#      scoop install git
#
# To install an app from a manifest at a URL:
#      scoop install https://raw.github.com/lukesampson/scoop/master/bucket/runat.json
#
# To install an app from a manifest on your computer
#      scoop install \path\to\app.json
#
# When installing from your computer, you can leave the .json extension off if you like.
#
# Options:
#   -a, --arch <32bit|64bit>  Use the specified architecture, if the app supports it
#   -i, --independent         Don't install dependencies automatically
#   -g, --global              Install the app globally
