# 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

#   INTLTOOLIZE_FLAGS - command line arguments to pass to intltoolize

#   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.
