# SEBS file for protobuf.
#
# A very long time ago (circa Aug 17, 2009), this was a valid SEBS file
# for building Google Protocol Buffers. In order to use it, you would
# put the file at `src/google/protobuf/SEBS` under the protobuf source
# tree. When cross-compiling, SEBS would intelligently build the
# protobuf complier (protoc) for the host system rather than the target,
# so that it could then be executed as part of the same build run to
# generate source code.
#
# This file almost certainly does not work today. It maybe worked with
# protobuf 2.2.0, if you want to sync back in time to try it.
# ====================================================================
# **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.
_cpp = sebs.import_("//sebs/cpp.sebs")
