Building rpms for FC3 ?

[Kim Lux]

I use a number of packages that don't ship with FC3: qcad, xcircuit,
etc.  The suppliers of these packages usually offer rpms for certain
distros.  I've never built an rpm before.  Is it worthwhile for me to
build an FC3 RPM and share it with the package suppliers ?  Or should I
leave this for the package developers to do, if and when they get FC3
installed ?

Is there anything I need to watch out for if I do build rpms ? 

Thanks.
