remove an installed rpm during rpm -i

[Barry R Cisna]

Hello List,

I've looked high and low and all the .spec file examples do not show how
to do this IF it is at all possible. How could I do an .spec file entry ,
possibly
%pre   --- something
to parse the rpm database and if a particular rpm is found to be installed
it will be uninstalled during the rpm install process? This is so my
rpmbuild/ rpm -ivh does not conflict with a few already exsiting /bin
files.
I am rolling a few binaries  into my rpm that would conflict with already
installed .rpm. I'm just trying to make this as streamlined as possible.

Thanks,
Barry
