* @short_description: Base class for C extensions.
* @see_also: #BeanPluginInfo
*
* #BeanExtensionBase can optionally be used as a base class for the extensions
* of your plugin. By inheriting from it, you will make your extension able to
* access the related #BeanPluginInfo, and especially the location where all
* the data of your plugin lives.
*
* Non-C extensions will usually not inherit from this class: Python
* plugins automatically get a "plugin_info" attribute that serves
* the same purpose.
