The [opGenerate:module|INFO] task creates the basic directory structure
for a new module in an existing OpenPNE plugin application:

  [./symfony opGenerate:module opSamplePlugin pc_frontend sample|INFO]

The task can also change the author name found in the [actions.class.php|COMMENT]
if you have configured it in [config/properties.ini|COMMENT] or
[%sf_plugins_dir%/config/properties.ini|COMMENT]:

  [[symfony]|NONE]
    name=OpenPNE
    author=Your Name <youremail@example.com>

You can customize the default skeleton used by the task by creating a
[/lib/task/skeleton/module|COMMENT] directory.

If a module with the same name already exists in the application,
it throws a [sfCommandException|COMMENT].
