GumpCommandLineOptions.

All Gump scripts (currently) have the same commandline:

   python gump.py \[options\] -w \{workspace\} \{project expression\}
   python bin/XYZ.py \[options\] -w \{workspace\} \{project expression\}

Available:

• -w {workspace file} — reference to workspace file.
• {project expresion} — e.g. 'all'

Options:

• d|-debug – turn on Gump debugging
• v|-verbose – not much different than above right now.
  

Proposed:

• --optimized – only compile things if updated
• --cached – allow cached descriptors (don't download over HTTP, and certainly don't CVS update)
