[Rpm-maint] rpmrc format

[Lucas Brasilino]

Hi!

I'm trying to setup an environment to build some RPMs as myselft
but couldn't find the right ~/.rpmrc file format.
I've tried many options:

%{topdir}: /home/lucas/rpm
%{tmppath}: /home/lucas/rpm/tmp

%{_topdir}: /home/lucas/rpm
%{_tmppath}: /home/lucas/rpm/tmp

topdir: /home/lucas/rpm
tmppath: /home/lucas/rpm/tmp

_topdir: /home/lucas/rpm
_tmppath: /home/lucas/rpm/tmp

None works. Which can I set up ~/.rpmrc file?

Please CC direct to me.

bests regards
