[Scribus] PyQt for Scripting

[el Sismógrafo, S.L.]

I have started to write some scripts for imposition. They are all right for me 
because I always use the same bleeding width, the same colors and length for 
crop marks, etc. To be quite honest I would like to parametrise them to make 
them usefull for other people as well so I have started to try with PyQt for 
making input dialogs, but I don't get it working. Any code snippets available 
to get an idea of how to do it?
