You can't just run cswig directly on a header file.  You have to use 
gccxml to first produce xml output.  Then you have to use cableidx to 
produce "index" files.  FYI, CableSwig was written specifically to wrap 
ITK and is not really supported outside of that purpose.  That's why 
there isn't much documentation.  The only place I can tell you to look 
for help is in the ITK source tree under Wrapping/CSwig for an example 
wrapping configuration (though very complicated).

If you are interested specifically in python wrapping (and not other 
languages) then you may want to look at pyste 
(http://www.boost.org/libs/python/pyste).  It uses the same parser 
(gccxml) as CableSwig but produces Boost.Python wrappers instead of SWIG 
wrappers and it has better documentation.
