LaTex - the document processing system.
There are plenty of good sites on the web on how to use
LaTex etc.Here we just list how to get started.
Installation
Download and install the latest version of
MikTex.
You will also need an editor to edit the files - we suggest
WinEdt or (insert name of other package). Again both can just be downloaded off the web.
