# Usage
###############################################################################
# This script uses a config file that can be used to stash common arguments
# passed to configure or environment variables that need to be set before
# configure is called.  The configuration file is a simple shell script that
# gets sourced.
#
# By default, the config file that is used is named 'autogen.args'.  This can
# be configured below.
#
# Available options that are handled are as follow:
#   ACLOCAL_FLAGS - command line arguments to pass to aclocal
#   AUTOCONF_FLAGS - command line arguments to pass to autoconf
#   AUTOHEADER_FLAGS - command line arguments to pass to autoheader
#   AUTOMAKE_FLAGS - command line arguments to pass to automake flags
#   CONFIGURE_FLAGS - command line arguments to pass to configure
#   GLIB_GETTEXTIZE_FLAGS - command line arguments to pass to glib-gettextize
#   LIBTOOLIZE_FLAGS - command line arguments to pass to libtoolize
#
# Other helpful notes:
#   If you're using a different c compiler, you can override the environment
#   variable in 'autogen.args'.  For example, say you're using distcc, just add
#   the following to 'autogen.args':
#
#       CC="distcc"
#
#   This will work for any influential environment variable to configure.
