## The Tracking Script

> The source of the tracking script is hosted on
[GitHub](https://www.github.com/skroutz/analytics.js).

The tracking script, registers a new global function named `<%= "#{flavor}_analytics" %>`, and then
asynchronously loads the `analytics.js` library onto the page.

The `<%= "#{flavor}_analytics" %>` global function is the main way you interact with the Analytics library.
It accepts a sequence of parameters, that represent:

Category
: The API category

Command
: The Command of the API category you want to be executed

Data
: The Data to be reported by the Command

> ##### Note
> *Categories* and *Commands* are **case-sensitive**.
