Installing Jasmine with Composer.

composer.json

{
    "name": "My jasmine-enabled project",
    "description": "A project which installs Jasmine into vendors",
    "repositories": [
        {
            "type": "package",
            "package": {
                "name": "pivotal/jasmine",
                "version": "1.3.1",
                "dist": {
                    "type": "zip",
                    "url": "https://github.com/pivotal/jasmine/raw/master/dist/jasmine-standalone-1.3.1.zip",
                    "reference": "1.3.1"
                }
            }
        }

    ],
    "require": {
        "pivotal/jasmine": "1.3.1"
    }
}

The Jasmine Gem (https://github.com/pivotal/jasmine-gem) has an advantage over this approach in that the gem supports CI integration - it can programmatically read the spec runner's output using Selenium.

But for some situations, using Composer like this might be handy.
