37# Script for automatically preparing the sources for compilation by
38# performing the myriad of necessary steps. The script attempts to
39# detect proper version support, and outputs warnings about particular
40# systems that have autotool peculiarities.
41#
42# Basically, if everything is set up and installed correctly, the
43# script will validate that minimum versions of the GNU Build System
44# tools are installed, account for several common configuration
45# issues, and then simply run autoreconf for you.
46#
47# If autoreconf fails, which can happen for many valid configurations,
48# this script proceeds to run manual preparation steps effectively
49# providing a POSIX shell script (mostly complete) reimplementation of
50# autoreconf.
51#
52# The AUTORECONF, AUTOCONF, AUTOMAKE, LIBTOOLIZE, ACLOCAL, AUTOHEADER
53# environment variables and corresponding _OPTIONS variables (e.g.
54# AUTORECONF_OPTIONS) may be used to override the default automatic
55# detection behaviors. Similarly the _VERSION variables will override
56# the minimum required version numbers.
57#
58# Examples:
59#
60# To obtain help on usage:
61# ./autogen.sh --help
62#
63# To obtain verbose output:
64# ./autogen.sh --verbose
65#
66# To skip autoreconf and prepare manually:
67# AUTORECONF=false ./autogen.sh
68#
69# To verbosely try running with an older (unsupported) autoconf:
70# AUTOCONF_VERSION=2.50 ./autogen.sh --verbose
