Python

[pasty <pasty_camel yahoo com au>]

Hi,
Not sure if this is the best place to ask these questions, but here goes.
As new comer to Gnumeric, I'm trying hard to leave Microsoft's Excel 
behind.  Unfortunately, I've become rather reliant on a number of functions 
written in visual basic.  Transfering excel workbooks really means re- 
writing a number of functions.
When adding user defined functions, is it best to write python plugin 
modules (as described in the help manual) or is there another method?
If python plugins are the most suitable, is there a way of having gnumeric 
re-read the python plugin file without closing and re-opening?

Functions written in python plugin work real well.  It would be nice 
however, if Gnumeric could load a python function definition set written 
for a specific workbook, maybe embedded in the Gnumeric file, or saved to 
the same directory with the workbook's name and the .py file extension
Can user defined functions be called by the button wigets?

There is an entry in the Gnumeric manual under extending Gnumeric called 
"defining new functions".  Is this page empty because the feature hasn't 
been documented yet, or because the feature hasn't been implemented yet.
