  28 # Description
  29 #     Script to control distccd daemons. (distcc/distccd is a distributed
  30 #     C/C++ compilation frontend). Distccd daemons need to be running
  31 #     on all platforms one wants to build on. The platforms are specified
  32 #     in the DISTCC_HOSTS environment variable.
