I'm not sure I understand.  What is it that autogen does (sample input X
leads to output Y when run like Z) and what is it that you want
Automake (or another tool) to do (input X leads to output Y)?  Do you
intend to write a patch for Automake, or is this something purely
external for one specific project, or to be more generally usable for
all users of Autogen inside a project using Automake for building?

Thanks,
Ralf
