Eeb development -- use the internet to call the shell to compile a latex file?

Hi

I have a webpage that displays a latex .tex file. I would like to be able to compile this latex .tex file online.

In order to compile a latex file via the shell one needs to type the following:

> latex onlinefile.tex

this will compile the file and produce two files:  onlinefile.ps and onlinefile.dvi. I would like to be able to compile the onlinefile.tex file by clicking a submit button on my webpage.

How can I achive this?

Thanks.
