amber and namd

 I am exploring using NAMD to run dynamics and want to run some
 comparisons. I currently use amber/sander so I have topology/coordinate
 files in amber format.  I know NAMD can use these and that a config
 script/file has to be set up.  Being lazy, I was wondering if someone
 had such a file that would run a dynamics run with amber
 topology/coordinate files under NAMD.  Thanks.
