-    Attention 1.
-    To use Symfony2 standards to check coding you have to:
-    copy, symlink or check out repo to a folder called Symfony2 inside the phpcs Standards directory.
-
-    Example:
-    $ pear config-show | grep php_dir
-    $ cd /path/to/pear/PHP/CodeSniffer/Standards
-    $ git clone git://github.com/opensky/Symfony2-coding-standard.git Symfony2
-
-    Attention 2.
-    PSR2 standard is used instead of Symfony2 standard, because after installation squizlabs/php_codesniffer package
-    via Composer the Symfony2 standard is not included / available in this package. In this case the PHP Coding
-    Standards Fixer (http://cs.sensiolabs.org) is used.
