an option to make it more variable would be pleasing.
Namespaces as subdomain for example and no need to hardwire the
NS_FILE => "/wiki/file/$1",
NS_HELP => "/wiki/help/$1"
would be nice. Actual every addition of namespaces need an modification of the config, it would be awesome that it isn't needed in future versions. I use several, a couple douzen, to set all manually shouldn't be the way to go.
