To reduce http requests, I'm combining all scripts that my theme uses into a single minified .js file each time theme options is saved.
One of the files in this .js is the jQuery library.
Rather than including jQuery as a separate file (using wp_enqueue_scripts), I'm including the wordpress core jquery file as part of the output stream of this master .js file
The problem is that since I'm not using wp_enqueue_scripts() to load jQuery, there's is a possibility it can be included more than once on the page via a plugin that does not know its already there.
Can I set a flag so that WordPress knows that file already exists on the page?
