	Usage: $0 {configure|make|install|dist|distcheck|package|flags|bootstrap} [--xxx=yyy]

	$0 is a wrapper to invoke GNU 'configure' with options that match
	common conventions associated with this machine (i.e. $CFENV)

	You may also, if you wish, supply additional 'configure' options in
	their usual '--xxx=yyy' form.

	It will also build, make, install or create packages for the
	build environment.

	$0 does not know how to create packages for every environment,
	nor is the information on "common conventions" necessarily correct.
	Patches to this process are solicited -- especially in these areas.

	!
  if
    [ -x ./configure ]
  then
    echo "Legal configure arguments are:"
    ./configure --help
  fi
  exit 1
}
#
#	The vast majority of cases here have not been tested yet...
#	If you don't think the treatment of your favorite OS is right,
#	then submit a patch.  Some of these conventions were wild guesses...
#

#	autoconf "--enable-XXX" options generally have their default {yes|no}
#	set, and perhaps acted upon, in "configure.in".
#
#	But we will also allow many of them to take a "try" setting,
#	interpreted there as:
#		"try to act as if 'yes' had been specified, but if this proves
#		troublesome, then continue as if 'no' had been specified".
#	By using these from here in "ConfigureMe", this allows the beginner
#	to make rapid, successful progress (albeit suboptimal) with an
#	implicit sense of achievement, rather than the demoralisation from
#	an unnecessarily failed 'yes' specification.
