Lets say I download the file obtainable from the "Download Source" option at this link, http://arxiv.org/format/hep-th/9711200v3
How do I run such a Harvmac file?
Searching for Harvmac gives me this link, http://www.ctan.org/tex-archive/macros/plain/contrib/harvmac From this link I can download the "harvmac.tex" file but then what?
