Debbugs, SOAP and Usertags

A small bit of info that can be hard to find: It's possible to call debbugs' SOAP get_usertag function passing only an user as argument, to get all usertags set for this user and all bugs with each of these tags, like this:

>>> import SOAPpy
>>> proxy = SOAPpy.SOAPProxy("http://bugs.debian.org/cgi-bin/soap.cgi", "Debbugs/SOAP/V1")
>>> proxy.get_usertags("bts-link-upstream@lists.alioth.debian.org")
