# - Unified Makefile for XviD for *nix environments -
#
# Copyright(C) 2003 Edouard Gomez <ed.gomez@free.fr>
#
#
# Description:
#  This Makefile allows building XviD sources to obtain a shared library
#  and a static library. This Makefie uses variables defined in the
#  platform.inc file. This platform.inc file is usually created by the
#  ./configure script whenever a unix shell is available.
#
# Nota Bene for mingw32/djgpp users:
#   However if you provide a platform.inc file adapted to your OS, then
#   change the include platform.inc to include yourfile.inc and it should
#   work too.
