+ * This tests your codebase for missing i18n strings so you can avoid error strings at render time
+ *
+ * It was taken from https://gist.github.com/Michaelvilleneuve/8808ba2775536665d95b7577c9d8d5a1
+ * and modified slightly to account for our Ignite higher order components,
+ * which take 'tx' and 'fooTx' props.
+ * The grep command is nasty looking, but it's essentially searching the codebase for 3 things:
+ *
+ * tx="*"
+ * Tx=""
+ * translate(""
+ *
+ * and then grabs the i18n key between the double quotes
+ *
+ * This approach isn't 100% perfect. If you are storing your key string in a variable because you
+ * are setting it conditionally, then it won't be picked up.
