// NOTE: If you want a different path, you need to add that path (relative path up to the 
// admin directory: ../dir or full path up to the admin directory: /full/path/to/dir) in 
// the first if statement in this config.php file - for example:
// && ($relative_script_path != "../dir") // relative path
// && ($relative_script_path != "/full/path/to/dir") // full path
// You may also need to set $relative_script_path to this path in search.php, clickstats.php, 
// and function_phpdig_form.php depending on what files you are calling from where
// NOTE: double dot means go back one and single dot means stay in same directory
// NOTE: the path should be UP TO but NOT INCLUDING the admin directory - NO ending slash
/***** Example
* PhpDig installed at: http://www.domain.com/phpdig/
* Want search page at: http://www.domain.com/search.php
* Copy http://www.domain.com/phpdig/search.php to http://www.domain.com/search.php
* Copy http://www.domain.com/phpdig/clickstats.php to http://www.domain.com/clickstats.php
* Set $relative_script_path = './phpdig'; in search.php, clickstats.php, and function_phpdig_form.php
* Add ($relative_script_path != "./phpdig") && to if statement
