   5 # This is an experimental build definition file using the SEBS build system.
   6 # I (Kenton Varda, maintainer of Protocol Buffers) happen to be the author of
   7 # SEBS, though SEBS is not a Google project.  I'm sticking this file in
   8 # protobuf's SVN because that's the easiest place for me to put it, and it
   9 # shouldn't harm anyone.  This file is not included in the distribution.
  10 #
  11 # Currently, to use this file, you must generate config.h and put it at the
  12 # top level of the source tree.
