cws-commit-patch - automate the creation of CWSes
Usage: cws-commit-patch ...params... patch1.diff patch2.diff ...

  -i, --iz        IZ number (XXXX or iXXXX)
  -c, --cws       CWS name (to be created or existing)
  -d, --default   Default to the latest milestone in MWS $default_mws
  -h, --help      Help
  -m, --milestone Milestone to base the CWS on (when -d is not used)
  -r, --root      cvs root
  -s, --summary   Summary describing the change (for cvs commit)
  -w, --mws       MWS (Master Workspace) (when -d is not used)
  
Eg. cws-commit-patch -i 1234 -c fix01 -d -r :pserver:me\@localhost:/cvs \\
                     -s \"Fixes this and that\" fix01-patch.diff
