###
#
# Script for automatically preparing the sources for compilation by
# performing the myriad of necessary steps. The script attempts to
# detect proper version support, and outputs warnings about particular
# systems that have autotool peculiarities.
#
# Basically, if everything is set up and installed correctly, the
# script will validate that minimum versions of the GNU Build System
# tools are installed, account for several common configuration
# issues, and then simply run autoreconf for you.
#
# If autoreconf fails, which can happen for many valid configurations,
# this script proceeds to run manual preparation steps effectively
# providing a POSIX shell script (mostly complete) reimplementation of
# autoreconf.
#
# The AUTORECONF, AUTOCONF, AUTOMAKE, LIBTOOLIZE, ACLOCAL, AUTOHEADER
# environment variables and corresponding _OPTIONS variables (e.g.
# AUTORECONF_OPTIONS) may be used to override the default automatic
# detection behaviors. Similarly the _VERSION variables will override
# the minimum required version numbers.
#
# Examples:
#
# To obtain help on usage:
# ./autogen.sh --help
#
# To obtain verbose output:
# ./autogen.sh --verbose
#
# To skip autoreconf and prepare manually:
# AUTORECONF=false ./autogen.sh
#
# To verbosely try running with an older (unsupported) autoconf:
# AUTOCONF_VERSION=2.50 ./autogen.sh --verbose
#

# Christopher Sean Morrison <[email protected]>
