/* This is the script that post-processes the results of `dumpgrepper` into wikitext for posting on mediawiki.org. It helps if you use the `git-mediawiki` package (https://github.com/Git-Mediawiki/Git-Mediawiki/wiki) to sync the results back onto mediawiki.org.
 * 1) !/usr/bin/node

Usage: 1. Put the output of `dumpgrepper` into a subdirectory named `results/`. 2. Check out the pages from mediawiki.org using: git clone -c remote.origin.categories='Parsoid' -c remote.origin.mwLogin=[your mediawiki username] -c remote.origin.mwPassword=[your mediawiki password] mediawiki::https://www.mediawiki.org/w 3. Run: ./munge.js 4. Change to `w/`: git add. &amp;&amp; git commit &amp;&amp; git push var fs = require('fs'); var path = require('path'); var https = require('https');
