Location of kimpersonate code?

[Daniel Joseph Barnhart Clark <dclark@pobox.com>]

I'm updating my page on Samba to AFS connectivity [1] and recently found 
discussion of using kimpersonate for that purpose, which IMHO looks better 
than the other alternatives I am aware of at the moment.

I'd like to test the solution and maybe write up some doc, but I can't seem 
to find the kimpersonate code in either the heimdal or arla distributions - 
does anyone know of the location or have a copy they would be willing to 
share?

[1] TWiki  . AFSLore  . SMBtoAFS : kimpersonate

Thanks,
