  37 # Script for automatically preparing the sources for compilation by
  38 # performing the myrid 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
