  @shortdoc "Archives the project and all it's dependencies into .ez files"

  @moduledoc """
  Builds each dependency required by the project and the project itself into
  archives according to the specification of the
  [Erlang Archive Format](https://www.erlang.org/doc/man/code.html).

  This task goal is to create packages. which could
  be used from Erlang environment without Elixir installation.

  The archives will be created in the "archives" subdirectory of
  the project build directory by default, unless an argument `-o` is
  provided with the directory name.

  The task will create archives for the project application,
  and all it's dependencies.

  If `-e` flag is specified, it will also archive elixir core applications
  referenced by the project and all it's dependencies.

  ## Command line options

  * `-o|--destination` - specifies output directory name.
      Defaults to BUILD_DIR/archives

  * `-e|--elixir` - specifies if all elixir applications
      should be archived. Defaults to `false`

  * `--skip` - a space-separated list of dependencies to skip
