Running Two Very Different Travis Builds

I have a project that's been happily chugging along on Travis for a while. Its .travis.yml looks something like

script:
  - node_modules/ember-cli/bin/ember test

I wanted to add a second parallel build that did something very different. I didn't want to run ember test with a different Ember version or some other flag. I wanted to run a completely different command. Specifically, I wanted to run LicenseFinder's audit.

Travis has great docs on customizing parallel builds, but nothing describes how to do two completely different commands.

Convert a Word Document into MD

Converting a Word Document to Markdown in One Move

The Problem

A lot of important government documents are created and saved in Microsoft Word (*.docx). But Microsoft Word is a proprietary format, and it's not really useful for presenting documents on the web. So, I wanted to find a way to convert a .docx file into markdown.

Installing Pandoc

On a mac you can use homebrew by running the command brew install pandoc.
