RPM question

[Luc MAIGNAN]

Hi,

sorry for a so newbie question, but I can't find the answer in the howto
i've read.
I want to build a RPM to install a software i've written. In the .spec,
the %install tag seems to be executed when the rpm is built and not when
i  install it. Where can I put code in the spec file to execute it at
installation time ? (rpm -ivh)

Any help would be appreciated
Best regards
