-Integrating MathJax into a rails project however could be a pain. MathJax is HUGE. It makes your project folder swollen very much, because of the excessive amount of files contained in this package. Including mathjax inside your developing directory makes your TextMate less responsive, because when TextMate loses focus and then regains focus, it will scan the whole directory structure for change.

-Another problem is, where to put? Put into `public` does not seem the best practice, since beginning with rails 3.1 `public` is by default ignored in production environment. Plus it is big, when using git, it leaves you no choice but to throw mathjax inside .gitignore, which makes sharing across developers less painless.
