Jason,

I was assuming that the Studio developers would be doing something for
generating this config file in studio.  Actually, I have no idea how people
normally create these config files.

Having said earlier that creating the config file should be easy, I must
confess that on sober second thought I'm not exactly sure how I'm going to
approach it.  The GDAL PHP bindings and I'm not sure we want Web Studio
having a dependency on GDAL PHP bindings anyways.

In theory I suppose Web Studio can use FDO itself to get the bounds for
individual files and then build the config file based on that.  I presume
that is what Studio does?

So, I find myself backing off a bit and thinking perhaps I would offer
an output switch for my existing gdaltindex program that would provide
XML config files instead of shapefiles.

Best regards,
