12    """
13    This class defines the interface for a Plugin class
14    that can be used by the gui_manager.
15   
16    Plug-ins should be placed in a sub-directory called "perspectives".
17    For example, a plug-in called Foo should be place in "perspectives/Foo".
18    That directory contains at least two files:
19        perspectives/Foo/__init__.py contains two lines:
20       
21            PLUGIN_ID = "Foo plug-in 1.0"
22            from Foo import *
23           
24        perspectives/Foo/Foo.py contains the definition of the Plugin
25        class for the Foo plug-in. The interface of that Plugin class
26        should follow the interface of the class you are looking at.
