# 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 a different version of the app
# (note that this will auto-generate the manifest using current version):
#      scoop install gh@2.7.0
#
# To install an app from a manifest at a URL:
#      scoop install https://raw.githubusercontent.com/ScoopInstaller/Main/master/bucket/runat.json
#
# To install a different version of the app from a URL:
#       scoop install https://raw.githubusercontent.com/ScoopInstaller/Main/master/bucket/neovim.json@0.9.0
#
# To install an app from a manifest on your computer
#      scoop install \path\to\app.json
#
# To install an app from a manifest on your computer
#      scoop install \path\to\app.json@version
#
# Options:
#   -g, --global                    Install the app globally
#   -i, --independent               Don't install dependencies automatically
#   -k, --no-cache                  Don't use the download cache
#   -s, --skip-hash-check           Skip hash validation (use with caution!)
#   -u, --no-update-scoop           Don't update Scoop before installing if it's outdated
#   -a, --arch <32bit|64bit|arm64>  Use the specified architecture, if the app supports it
