Comment (by barry.wardell):

 An alternative which is already available is the rpar file format
 supported by SimFactory. That is, whenever SimFactory encounters a
 parameter file with the .rpar extension, it assumes it is executable and
 will produce a .par file with the same base name when executed. It then
 executes this file and runs Cactus with the generated .par file. This
 allows almost arbitrary flexibility, including constants and variables by
 writing rpar files in your language of choice (Python/Perl/etc.). There is
 an example of how this works in the sgw3d.rpar file in the McLachlan
