  25     wmget.c - main() and a few common functions
  26
  27     This file contains the main() for wmget; it simply checks for the
  28     presence of ``dock'' as the first argument and invokes server(),
  29     request(), cancel(), or list() as appropriate.  Also found here are
  30     a few global utilities.
