$pathroot

The $pathroot variable is similar to the $PATH_INFO environment variable set by the web server, except that it does not contain state or function/MIME-type information (see section 1.1.6 on URL syntax). $pathroot is the URL path (or file path if run from the command line) to the source of the current Vortex script. It is set once at script startup. The $pathroot variable was added in version 2.1.867816000 19970702.
