  119:    in this example when the multiple choice tag is hit, it put the
  120:    parser into buffer mode, as the parser hits the tags it internally
  121:    counts up the number of true/false responses and the number of
  122:    showrandomfoil, then it reparses it, this time actually parsing the 
  123:    foil sections and actively creating output at the show random foil tags

  128: <outtext>
  129: 
  130: all data is assumed to be html, we will attempt to autoconvert to
  131: whatever the output target is.
  132: 
  133: ------------------
  134: targetted output
  135: In all strings in the perl section and <outtext> blocks you can have
  136: 
  137: <target type="X" dest="Y,Z"> some text </target>
  138: 
  139: where X Y and Z are valid target for homework. Examples are web,tex,?pdf?,ascii
  140: 
  141: type defines what target the data is already formatted in, 
  142: 
  143: dest defines what targets it should be autoconverted for, (input
  144: format is assumed to be a valid output format).
  145: 
  146: If the current target isn't a possible dest, the data will be ignored.
  147: 
  148: Shorthand:
  149: <tex> </tex> == <target type="tex"> </target>
  150: <tex dest="web"> </tex> == <target type="tex" dest="web"> </target>
