The [plugin:uninstall|INFO] task uninstalls a plugin:

  [./symfony plugin:uninstall sfGuardPlugin|INFO]

The default channel is [symfony|INFO].

You can also uninstall a plugin which has a different channel:

  [./symfony plugin:uninstall --channel=mypearchannel sfGuardPlugin|INFO]

  [./symfony plugin:uninstall -c mypearchannel sfGuardPlugin|INFO]

Or you can use the [channel/package|INFO] notation:

  [./symfony plugin:uninstall mypearchannel/sfGuardPlugin|INFO]

You can get the PEAR channel name of a plugin by launching the
[plugin:list] task.

If the plugin contains some web content (images, stylesheets or javascripts),
the task also removes the [web/%name%|COMMENT] symbolic link (on *nix)
or directory (on Windows).
