 A lexer and highlighter for [_Mathematica_](http://wolfram.com/mathematica)/Wolfram Language
  source code using the [pygments](http://pygments.org) engine.
 
- This code is based on [pygments-mathematica](https://pypi.org/project/pygments-mathematica/) but has been specially revised so it interactis with [mathicsscript](https://pypi.org/project/mathicsscript/). As such it works better that pygments-mathematica for this use, and possibly might not be as good in other contexts. Over time though this should get address.

  Another difference, is the fact that this package is relegate knowledge about operator names to [Mathics-Scanner](https://pypi.org/project/Mathics-Scanner/).
