Dumps all or selected tracker items or forum threads stored in a SourceForge XML backup file as plaint text to standard out or into a file.
To get usage information, run:
$ python dump.py --help
Personally I used this script for easy migration of some hand-selected tracker items and forum threads to a GoogleCode issue tracker system.
How to get the SourceForge XML backup file
In your SF project go to Project Admin → Feature Settings and then select XML Export of the Backup feature.
Verify that the exported XML file is valid! In my case it was malformed and I had to remove some tags (which had no matching close tag) manually.
