 urpmb expects all required sources and patches to build the rpm(s) from the
 specified specfile to be in the same directory as the specfile.

 urpmb will create a directory called RPMS in the current directory where
 all created *.rpm files will be placed.

 options:
  -s   sign the package

 rpmbuild_options: (passed to rpmbuild)
  -ba  build binary and source packages (default)
  -bb  build binary package
  -bp  executes the "%prep" stage from the spec file
  -bc  do the "%build" stage from the spec file
  -bi  do the  "%install"  stage  from  the spec file
  -bl  do a "list check"
  -bs  build just the source package
