php-cs-fixer: need more information on using fix --level option

Now in 2017, since version 2, you can use describe command.

vendor/bin/php-cs-fixer describe @PSR2

It shows you current fixers in the ruleset with names and description:

enter image description here

So for "Symfony" ruleset it would look like:

vendor/bin/php-cs-fixer describe @Symfony

And for single rule like:

vendor/bin/php-cs-fixer describe some_rule

Also notice level option was deprecated. Use it as rule, just with @ prefix instead.

vendor/bin/php-cs-fixer --rules=@PSR2
