Usage: b2install-prepare [--non-interactive] [tools|light|basf2|build|externals|all]

This tool will check if all necessary packages are installed and if not it will
ask the user if they should be installed. If --non-interactive is given the tool will not
ask for confirmation but will just install the necessary packages.

The purpose for which the necessary packages are installed is given by one
of the following arguments:

  tools: for using the tools
  light: for using a (light) basf2 release, without graphics
  basf2: for using a full basf2 release, including graphics
  build: for building basf2 [default]
  externals: for building the externals
  all: for building the externals including optional packages

A given purpose includes all purposes earlier in the list.
