'''Script to export zim wiki pages to trac / mediawiki
To use it, call
python trac2zim.py notebook output_folder prefix
where prefix is a string you put before each wiki page name. It will
fill output_folder with plain text files ready to be loaded with trac-admin:
trac-admin /path/to/project wiki load output_folder
zim links like [[:Software:note taking:zim|zim]] are flattened to wiki
entries like [Software_note_taking_zim zim].
