[v2] header file conversion

Hi,
I need to preprocess some header files with a perl script. Say, I have 
"a.cpp" that includes "a.hpp", which needs to be created first from 
"a.h". I need to 1) run the perl script taking a.h and creating a.hpp 
and then to 2) compile a.cpp as part of the library. Also I need to keep 
track of the dependency between a.h and a.cpp.
It looks like I canot register a new generator, because the suffix ".h" 
is already assigned to a type "H". I do not own the ".h" files, thus 
renaming files with a different suffix is not an option.
It's no easier with the dependency: header scanner does not help, 
because a.hpp may not exist at a time of dependency calculation, so I 
think I need to state this dependency a.cpp->a.h explicitly in a 
Jamfile, but not sure how.
Any ideas?
Thanks in advance.
