  3.1 Sketch methods
  
  3.1-1 POLYMAKE_SKETCH_WITH_OPTIONS
  
  POLYMAKE_SKETCH_WITH_OPTIONS( arg1, arg2 )  operation
  Returns:  nothing
  
  This  method  produces  the  sketch  output from polymake. Sketch have to be
  installed to use this method. The first argument must be a polymake external
  object,  the  second  can  be  a  filename,  as a string, or a list of pairs
  specifying  polymakes  VISUAL options. In each pair the first entry needs to
  be  the  name  of  the  option,  the second should be the value it has to be
  given.  As  value  strings and lists of integers are allowed. Please see the
  polymake documentation for more informations.
  
  3.1-2 POLYMAKE_SKETCH_WITH_OPTIONS
  
  POLYMAKE_SKETCH_WITH_OPTIONS( arg1, arg2, arg3 )  operation
  Returns:  nothing
  
  This  works like the other POLYMAKE_SKETCH_WITH_DOCUMENTATION method but one
  can give a filename and options at the same time. Second argument here needs
  to be the filename, third the list of VISUAL option pairs.
  
  3.1-3 POLYMAKE_CREATE_TIKZ_FILE
  
  POLYMAKE_CREATE_TIKZ_FILE( arg1, arg2 )  operation
  Returns:  nothing
  
  Given a polymake object and a filename, this method produces the tikz output
  given by sketch and stores it in the file.
  
  3.1-4 POLYMAKE_CREATE_TIKZ_FILE
  
  POLYMAKE_CREATE_TIKZ_FILE( arg1, arg2, arg3 )  operation
  Returns:  nothing
  
  This  does  the  same as POLYMAKE_CREATE_TIKZ_FILE but the third argument is
  passed  to  the VISUAL command of polymake. It need to be a (possibly empty)
  list of options. The list must be consist of pairs, where the first entry is
  the  name of the option the second the value. As values strings and lists of
  integers are allowed.
  
  3.1-5 POLYMAKE_CREATE_TIKZ_FILE_WITH_SKETCH_OPTIONS
  
  POLYMAKE_CREATE_TIKZ_FILE_WITH_SKETCH_OPTIONS( arg1, arg2, arg3, arg4 )  operation
  Returns:  nothing
  
  Works like POLYMAKE_CREATE_TIKZ_FILE with 3 arguments, but the last argument
  has to be a string of options passed directly to sketch. For example, if you
  want to have a compilable tex file build, add "-T".
