The [plugin:install|INFO] task installs a plugin:

  [./symfony plugin:install sfGuardPlugin|INFO]

By default, it installs the latest [stable|COMMENT] release.

If you want to install a plugin that is not stable yet,
use the [stability|COMMENT] option:

  [./symfony plugin:install --stability=beta sfGuardPlugin|INFO]
  [./symfony plugin:install -s beta sfGuardPlugin|INFO]

You can also force the installation of a specific version:

  [./symfony plugin:install --release=1.0.0 sfGuardPlugin|INFO]
  [./symfony plugin:install -r 1.0.0 sfGuardPlugin|INFO]

To force installation of all required dependencies, use the [install_deps|INFO] flag:

  [./symfony plugin:install --install-deps sfGuardPlugin|INFO]
  [./symfony plugin:install -d sfGuardPlugin|INFO]

By default, the PEAR channel used is [symfony-plugins|INFO]
(plugins.symfony-project.org).

You can specify another channel with the [channel|COMMENT] option:

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

You can also install PEAR packages hosted on a website:

  [./symfony plugin:install http://somewhere.example.com/sfGuardPlugin-1.0.0.tgz|INFO]

Or local PEAR packages:

  [./symfony plugin:install /home/fabien/plugins/sfGuardPlugin-1.0.0.tgz|INFO]

If the plugin contains some web content (images, stylesheets or javascripts),
the task creates a [%name%|COMMENT] symbolic link for those assets under [web/|COMMENT].
On Windows, the task copy all the files to the [web/%name%|COMMENT] directory.
