php - How to install jQuery with Composer?

Question

I have been able to install repositories that do not have a composer.json file like this:

    {
        "type": "package",
        "package": {
            "name": "yahoo/yui-compressor",
            "version": "2.0.4",
            "dist": {
                "url": "http://yui.zenfs.com/releases/yuicompressor/yuicompressor-2.4.7.zip",
                "type": "zip"
            }
        }
    },

I took the "type": "zip" part from the docs, but I couldn't find many other types. For example, I need to install jQuery, but I don't know what to put in type ("js" did not work).

    {
        "type": "package",
        "package": {
            "name": "jquery/jquery",
            "version": "1.7.2",
            "dist": {
                "url": "http://code.jquery.com/jquery-1.7.2.js",
                "type": "js"
            }
        }
    }

Any ideas?

EDIT: I'm adding the full solution to help @CMCDragonkai:

    "require": {
        "vendorname/somefile": "1.2.3",
    },
    "repositories": [
        {
            "type": "package",
            "package": {
                "name": "vendorname/somefile",
                "version": "1.2.3",
                "dist": {
                    "url": "http://example.com/somefile.txt",
                    "type": "file"
                }
            }
        }
    ]

Actually there is an easier way to install jQuery, just type:

{
    "require": {
        "components/jquery": "1.9.*"
    }
}

It uses Component Installer for Composer and by default all assets from Component are installed under components, but it can be customize. (see docs).
