PNAS LaTex template

Thijs ten Raas's picture

Hi All,

My question is whether there is a Proceeding of National Academy of Sciences (PNAS) 2-column article shell available in SWP?

The PNAS webpage actually supplies template, style and class files at its webpage

but it's not clear to me how these would actually be installed in SWP (they do not mention it).

Any help would be greatly appreciated.
