This script builds RPMs for $NAME.

OPTIONS:

  --dist          Dist value for rpmbuild
                  Default is ${DIST}
  --mock          Run mock rebuild of SRPMs
  --rpmbuild      Run rpmbuild -ba
  --extract-spec  Extract spec file
  --debug         Show debug output
                  This option also removes the mock --quiet option.
  --trace         Show the mock debug output
  --noop          Do not execute commands
  -h, --help      Show this message

EXAMPLE:

Exract spec file without building (so can be modified)

$(basename $0) --extract-spec 14.03.6

Build SRPMs and run mock rebuild using existing spec

$(basename $0) --mock 14.03.6

Build SRPMs and run mock rebuild using packaged spec

$(basename $0) --extract-spec --mock 14.03.6

Build RPMs using existing spec

$(basename $0) --rpmbuild 14.03.6

Build SRPMs and run mock rebuild with existing spec and using custom dist

$(basename $0) --mock 14.03.6 --dist 1.el6
