%
%  Conjure interprets and executes scripts in the Magick Scripting Language
%  (MSL). The Magick scripting language (MSL) will primarily benefit those
%  that want to accomplish custom image processing tasks but do not wish
%  to program, or those that do not have access to a Perl interpreter or a
%  compiler. The interpreter is called conjure and here is an example script:
%
%      <?xml version="1.0" encoding="UTF-8"?>
%      <image size="400x400" >
%      <read filename="image.gif" />
%      <get width="base-width" height="base-height" />
%      <resize geometry="%[dimensions]" />
%      <get width="width" height="height" />
%      <print output="Image sized from %[base-width]x%[base-height]
%          to %[width]x%[height].\n" />
%      <write filename="image.png" />
%      </image>
