Just curious since sometimes I do things in xAct and then may want to do the same in Kranc and it would be nice if I could just say import xAct and the work done in it to a developing Kranc script.  Of course, there are several pieces of xAct, so maybe my question is not formulated precisely enough, but what do you think?

Hi,

There is experimental support in Kranc for using xAct as an input language.  However, it is not well-tested, and might be missing important functionality.  This was added by Barry Wardell some time ago.  In the past, I have converted xAct expressions into the format expected by Kranc using some simple replacement rules.  Let me know if you would like an example.  Barry might be able to provide more details of the xAct support in Kranc; I'm not sure of the current status.
