Speech Text

[Leela Bala]

Hi

I have three queries:

1. Shall I convert the below js into exe, and is it possible to use the exe in another system without installing NodeJS

2. How should include the speech text with the same code, I am using convert tex2mml-page

3. I need <mfenced tag instead of <mo fence="true", how should i do this.

I am using the below code.

#! /usr/bin/env node
