Usage:
  genbuild complist1 [complist2 ...]   -- generate build scripts

Given a list of components, generate the scripts necessary to
build them all using the automated build system. The scripts 
will be named after the component list, so

  genbuild \\batch\\build\\somename.txt

will generate the following scripts:

  somename_bldfiles.cmd    - run "bldmake bldfiles" on every component
  somename_export.cmd      - run "abld export" on every component
  somename_makefile.cmd    - run "abld makefile" on every component
  somename_library.cmd     - run "abld library" on every component
  somename_resource.cmd    - run "abld resource" on every component
  somename_target.cmd      - run "abld target" on every component
  somename_final.cmd       - run "abld final" on every component
  somename_check.cmd       - run "abld -check build" on every component
  somename_what.cmd        - run "abld -what build" on every component
  somename_clean.cmd       - run "abld clean" on every component
  somename_reallyclean.cmd - run "abld reallyclean" on every component

  somename_build.cmd       - use appropriate combination of above scripts
  somename_pbuild.cmd      - alternative build script for multi-machine builds

The somename_build.cmd script is controlled by options specified in the
list of components, and calls the other scripts in the correct sequence.
