$	! Very simple for the moment, it will take the following arguments:
$	!
$	! -32 or 32	sets /POINTER_SIZE=32
$	! -64 or 64	sets /POINTER_SIZE=64
$	! -d		sets debugging
$	! -h		prints a usage and exits
$	! -t		test mode, doesn't run Configure

Usage: @config [options]

  -32 or 32	Build with 32-bit pointer size.
  -64 or 64	Build with 64-bit pointer size.
  -d		Build with debugging.
  -t            Test mode, do not run the Configure perl script.
  -v            Verbose mode, show the exact Configure call that is being made.
  -h		This help.

Any other text will be passed to the Configure perl script.
See INSTALL.md for instructions.
