Here's what I did to make this site.

I assume you have Stata and Mercurial/TortoiseHg.

Create new project on http://code.google.com (In my case, http://code.google.com/p/kk-adofiles/) Initialize project on my computer.

 cd C:\Projects\code.google.com\
 hg init kk-adofiles

Run my -pub2web- program from Stata

. pub2web pub2web memmax did3 <other packages> ///
    using "C:\Projects\code.google.com\kk-adofiles" ///
    , replace author("Keith Kranker") ///
    intro("Programs by Keith Kranker, Ph.D. Candidate, Department of Economics, University of Maryland ")

Commit repository and push

 hg add 
 hg commit -m"My message"
 hg push https://kk-adofiles.googlecode.com/hg/kk-adofiles 

Optional: Add project description and wiki pages at code.google.com
