Glen Whitney 77bd983cbc feat: install moo and use in toy example 
I failed to find a satisfactory way to compile and import moo.js with
   fixed specifiers, so finally I just gave up and patched the distributed
   code to be an es6 module. A bit ugly but it works.

vrml1to97

JavaScript converter from VRML 1.0 to VRML97 file format, based on Wings 3D conversion logic.

Essentially, this is a JavaScript reimplmentation of the algorithm of the "token rearranger" found in the Wings 3D x3d importer (which was written in Erlang).

Usage

From an es6 module

import {convert} from 'vrml1to97'
const vrml1spec = '# VRML 1.0 ....'
const vrml97spec = convert(vrml1spec)

or from a script

(async () => {
   const vrml1to97 = await import('./dist/vrml1to97/index.js')
   const vrml1spec = '# VRML 1.0 ....'
   const vrml97spec = vrml1to97.convert(vrml1spec)
})()

or from the command line via node
