Where exactly is the document root in my openshift server?

I'm trying out OpenShift for the first time. I'm using the php-5.4 cartridge and I'm trying to deploy a Laravel project.

Laravel requires the document root to point to the public directory which is one level into the framework structure.

I see here that php cartridge's document root could be any of several specific directory names including public.

The problems I'm having are that:

1. Once I push my project to the server, openshift doesn't seem to see the public folder automatically.

2. I can't find the webroot itself.

When I ssh into the server and list my home directory I see the following directories:

    app-deployments
    app-root
    git
    php

I thought the php directory would be the root that the docs talk about, but that seems to contain all of the configurations for php itself. I then figured it may be in app-root or app-deployments, but when I grep -Ri Laravel * in my home to look for anything with laravel in it (like the readme) but I get nothing in return (and I know I pushed to the server).

---

I know and believe that the php cartridge will programmatically look for the directory names to determine the root, but where does it start that search? If there's a specific spot in the documentation where it's explained, could someone post the link to it because I can't seem to find it?

Edit

I should also add that I tried to check the normal linux /var/www directory, but my user doesn't have access to the directory and my user is not (at least I don't think I am) a super user.

Try: grep -D skip -Ri Laravel *
It should be in: ~/app-root/runtime/repo
