What's the use case? Especially for php based config? :)

I have a new project where I've setup the services using the fluent PHP based configuration introduced in symfony/symfony#23834.

With this format the IDE provides better code completion suggestions and I can rename classnames declared in configuration files using the Refactor feature included in the IDE.

I've added support for XML format after seeing #10

Thank you for your contribution!

This depends on the IDE. Phpstorm with the Symfony plugin does a really good job for me.

With auto wiring support and minimal amount of config you need to add, I don't see a point of using php or xml. Especially in a behat extension. Nevertheless, I can understand to some it's appealing and I'm probably gonna merge this in ;)

Thank you @ajgarlag!

Included in the v2.1.0 release.

Thank you @jakzal for merge and quick release.

There is an error in the release note:

Ignore development files from git export (#16) / thanks @ajgarlag

@ajgarlag copy&paste is the source of all evil :P fixed!
