XITE license

[Ole Kristian Aamot]

I would like to use some C algoritms for image analysis - that are
implemented in a software kit, that some claim is "free software",
written by researchers employed by the Image Processing Laboratory, 
at Department of Informatics, University of Oslo.

I'm an undergraduate at the Department of Matematics, and the co-
developer of gPhoto, the GNU digital camera utility in GNOME CVS.

One of the CS researchers, Svein Bøe, claims that their license is
"not the same as the GNU GPL".  (That should mean I can't use it?)

I don't really understand why a research project should stop
development of GNU software - if the proper credit is given?

I realize it is a BSD license - but I just want to know how
it (in theory) could be changed to comform with the GNU GPL.

I have studied the sources, but I'm unable write an implementation
myself without indirectly or partly using XITE sources & routines.

I don't know the mighty research theory behind them sources.  Yet.

Thanks.
