Perl RPM Requires/Provides

[Dave Cross]

As I understand it, the current version of rpmbuild works generates the 
Requires and Provides definitions for an RPM by parsing the Perl code 
and working out which modules are used (for Requires) or defined (for 
Provides).

I don't want to get into a discussion of the rights or wrongs of this 
approach, but for my own RPMs, I'd like to experiment with creating the 
Requires and Provides definitions by parsing the META.yml file.

I've found three files in /usr/lib/rpm - perldeps.pl, perl.prov and 
perl.req - which seem to do the work, so I assume these are the files 
I'll need to replace.

Can someone please confirm that these are the files that I need to work 
on and (even better) point me at some documentation for how these 
programs are called - what inputs and outputs are expected, stuff like that.

Also, is there a way to provide my own replacement for these files 
without just overwriting them. I'd rather not fiddle directly with 
system supplied code.

Any advice appreciated.

Cheers,

Dave...
