[Python-Dev] PEP 376 proposed changes for basic plugins support

I think both are necessary. A discovery API should be available, but the
library or application should be free to do whatever it wants with the
discovered plugins - enable them automatically, present them to the
user, or nothing.

(a GUI application, for example, needs to be able to display a list of
available plugins, with checkboxes to enable or disable each of them. It
is not reasonable to expect the user to type the plugin name in a
textbox)
