To install this site:
1) Create a web site called "Chai and Chaat Wiki".
2) In that site, create a virtual directory '/moin_static185' that points to htdocs.
3) Assign Full Control (or at least write) permissions for the "Chai and Chaat Wiki" application pool account (probably 'IIS AppPool\Chai and Chaat Wiki') to .
icacls . /grant "IIS AppPool\Chai and Chaat Wiki:(OI)(CI)(IO)(F)"
icacls . /grant "IUSR:(OI)(CI)(IO)(F)"
4) Install the ISAPI extension using "./moin-isapi-wsgi.py install".
Eventually, I'll write a script to do these things.
