[Qgis-developer] A common set of functions for QGIS plugins

[Neumann, Andreas]

Hi, 

The upcoming user conference in Girona may be a good opportunity to
present and advertise about both the common set of Python functions, but
also about the standard and custom widgets. 

The CfP is still running and they are looking for more submissions.
Maybe someone could do a presentation for Python plugin authors to make
them aware?
