Description of problem:
The rpm library do not provide informations about the CFLAGS or
library needed for linking. Those have been changing on a regular
basis. To avoid future problems please provide a shell script
rpm-config installed as part of rpm-devel providing and accepting
the following flags:
  --libs                print library linking information
  --cflags              print pre-processor and compiler flags

  This is trivial to do (rpm-config.in generating rpm-config as
part of rpm configure process), and will allow applications using
the rpm library to 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.install 7.3, try to link rpm2html against librpm
2.install 8.0, try to link rpm2html against librpm
3.install rawhide, try to link rpm2html against librpm

Actual Results:  a friggin mess

Expected Results:  rpm-config --cflags whould return the set of gcc -I options
needed to compile code dependant on librpm
rpm-config --libss whould return the set of gcc link options
needed to link code dependant on librpm

an attempt for a patch providing rpm-config functionalities

This doesn't work as is, using @LIBS@ directly gets too many libraries.
This at least shows how this could work, might need some tuning to be made

this would be IMMENSELY helpful for the perl-RPM2 package.

better than a separate script would be to use pkg-config.  it's really easy...
just drop a file in /usr/lib/pkgconfig that has the data in it.  it's so trivial
but would really help anyone who has to link against rpm.

don't know how far pkgconfig goes back, though, so maybe a separate script would
be good.
