[Qgis-developer] Plugin requirements

[Luigi Pirelli]

Hi Xavier

1) pip can be installed on OSGeo4W (many references on the gis stack
exchange and on the web)
2) paver do nothing other than creating python eggs or now you can use
wheel format, then setting pythonpath starting the plugin allow you to
load module from local modules... paver is a utility to simplify
packaging

cheers

Luigi Pirelli
