middleman-targets version #{Middleman::MiddlemanTargets::VERSION}

This gem adds functionality to Middleman and is not executable on its own
(other than for generating the documentation sample project). Instead, you
must add this gem to your Middleman project's `Gemfile` and then activate
it in your `config.rb` file. This will enable the new `--target` command
line option in Middleman, and the new `build_all` command.

`documentation` will produce a sample project named `middleman-targets-docs/`
in your current working directory. This sample uses the features of this gem.
You can then serve this new project to read the documentation by:

cd middleman-targets-docs
bundle install
bundle exec middleman server
