-------------------

* Can now specify the width/height of postscript output, by passing (e.g.)
  width="5in" or height="10in" to the functions which \ 
produce postscript
  output. Default values are in the [postscript] section of config.ini.
  The old [printer]/paper option is now [postscript]/paper.

  with half-arrows indicating the true value is below/above the
  point.
