I'm not sure how boostrap implements popover. I have included bootstrap.js, and it has a function called Popover (upper case P), but in their example, they use:
$('#example').popover(options)
Now, they say it requires tooltip to be included, but I don't know what that means. Their examples all include a bunch of .js files and I think in reality they're all packaged up together.
And since I'm at the proof-of-concept phase, where I'm trying to get it to work right the first time, I'm not concerned about the file size or caching.
