autogen.mk

# Created: 2005/03/12
# Author: David Elliott

# Usage Example:
#  make -f build/autogen.mk ACLOCAL=aclocal-1.9

# This is a simple Makefile to update the UNIX build system in such a
# way that doing a cvs diff on its output files should reveal only the
# true changes, not meaningless differences due to slightly different
# autoconf or aclocal m4 files.

# For aclocal: All necessary m4 files are located in the build/aclocal
# directory.  Running aclocal -I build/aclocal when using aclocal 1.9
# will result in an aclocal.m4 which uses m4_include for these files.

ACLOCAL=aclocal
AUTOCONF=autoconf
BAKEFILE_GEN=bakefile_gen

# configure depends on everything else so this will build everything.
