I have an iPhone 4s that is still running iOS 5.1.1. Why is it not possible for me to update my device to  a newer version of ios without going all the way to the latest?


Question: any FAST tex to html program?
Answer: What about latex2html? It seems the only hit on Google that provides this kind of functionality. Keep in mind that latex is inherently slow, and it may be better to rely on something MathML or MathJax related. I have not tested the above for performance.

On Debian squeeze, just do

apt-get install latex2html
