The core of the GRAMPS plugin system. This module provides tasks to load
|
|
plugins from specfied directories, build menus for the different categories,
|
|
and provide dialog to select and execute plugins.
|
|
|
|
Plugins are divided into several categories. This are: reports, tools,
|
|
importers, exporters, and document generators.
