Object functions
Map functions
Other functions
There are several other things that needs documentation, for example all map and object attributes and all defined constants. For now, have a look at the example scripts in the map package or in the source code here or here.
PS. We need help testing and documenting the python plugin. Please contact me or the dev list if you feel that you can help. Also feel free to improve the layout of the reference. You can get the style sheet used here.
