+# 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
