# **EXPERIMENTAL**
#
# See http://sebs.googlecode.com
#
# This is an experimental build definition file using the SEBS build system.
# I (Kenton Varda, maintainer of Protocol Buffers) happen to be the author of
# SEBS, though SEBS is not a Google project. I'm sticking this file in
# protobuf's SVN because that's the easiest place for me to put it, and it
# shouldn't harm anyone. This file is not included in the distribution.
#
# Currently, to use this file, you must generate config.h and put it at the
# top level of the source tree.
