=============
Rule ``psr0``
=============

.. warning:: This rule is deprecated and will be removed on next major version.

   You should use ``psr_autoloading`` instead.

Classes must be in a path that matches their namespace, be at least one
namespace deep and the class name should match the file name.

.. warning:: Using this rule is risky.

   This fixer may change your class name, which will break the code that depends
   on the old name.
