I've inherited code for a project, Magento 1.9. For the task at hand, I need to touch a JavaScript file located at

```
skin/frontend/my_projects_name/default/release/js/script.js

```

This script was originally minified. To make changes, because I don't know how it was minified, I've used a program to "un-minify" it manually. Is this file common among Magento 1.9 projects, or is it unique to this codebase? There are several JS files. Which file was this minified from?

In the `skin/frontend/my_projects_name/default` dir, there are multiple dependencies files: 

* bower.json
* Gruntfile.js
* gulpfile.js
* package.json
