I've a C project set up in Hudson doing nighly builds, i've also an .rpm spec file used for creating rpms from these sources.

Does anyone have any experience on how to build rpms out of all this using Hudson ?

Right now the only solution I see is to set up a job running a script that checks svn exports the sources ,creates a tarball and does the whole rpm build. This doesn't seem to integrate well with Hudson - e.g. how do I collect the artifacts ?
