This is a one-off page to test if a given value is valid as the DOCUMENT_ROOT setting for LnBlog.

The page will attempt to guess the document root, but will also allow the user to enter one manually.  It will then use this path to build a local path and URI to the LnBlog ReadMe file.  The idea is that if the path to the ReadMe exists and the URI to access it works, then the DOCUMENT_ROOT is correct.
