Thanks to @K-Phoen for the linter.

We should a some more stuff :

• a helper or a command to run it locally ?
• in the README : how to run it locally to validate the changes

[K-Phoen]

Would it be easier for you if Rusty provided downloadable .phar executables? :)

[jubianchi]

@K-Phoen I'm not a super fan of Phar: it makes dealing with dependencie harder than with composer. Here we only have to put something in the json and composer deals with downloading, linking and locking everything ;)

[agallou]

ok. I will add both composer.json and composer.lock in the repository, and drop some lines about it in the readme.

PR updated with composer.json and composer.lock files commited, and documentation in README.md
