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.
