Need example spec file

[Steve Berg]

I'm trying to get my head wrapped around building rpms.  Can someone 
send me a spec file or link to one that would demonstrate how to 
structure the spec file for starting with a tar ball of files that need 
to be copied onto a system to something like /opt/<dir>.

There's no real build process to what I'm trying to do, no make/make 
install.  I just need to place a directory containing sub-directories 
and python scripts/files, one startup script in /etc/init.d/, a 
chkconfig <proc> add, and then start the python script which acts like a 
daemon.
