This is based on WebReflection/usignal, with some modifications.
I don't know if it even works or if it can be used for anything.
Install the gem and add to the application's Gemfile by executing:
$ bundle add usignal
If bundler is not being used to manage dependencies, install the gem by executing:
$ gem install usignal
TODO: Write usage instructions here
After checking out the repo, run bin/setup to install dependencies.
You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install.
To release a new version, update the version number in version.rb,
and then run bundle exec rake release,
which will create a git tag for the version,
push git commits and the created tag,
and push the .gem file to rubygems.org.
