This is by far the most complex of the Wacs XML commands as it has the most work to do. This command basically reads the Wacs XML file it is given, tries to find the matching zip or movie file, unpacks it, chooses a location for it, moves it there and adds it's details to the database. At it's simplest you use it as follows:

% wacsxmlin set417.xml
Destination Area: solo
Category: gallery010
%

It additionally supports two extra command line options, --clone which says put it exactly where the XML file says it came from and is ideal for copying content between in-house and production internet web servers. The other one is --default which merely does whatever the default answer would be on this site. For a site with gallery layout, this should pretty much do the right thing.
