title: How do I make rpmbuild only build subpackages?
body: <p>I am building a series of rpms from a single source and want to only build the subpackages; i.e. I don't want an empty main package created, only the subpackages.</p>
  
  <p>How do I do this?  is it an rpmbuild switch or something I put in to the spec file?</p>
  
  <p>thanks</p>
