    This file allows features to be easily enabled/disabled in config.php.
    Simply set variables for the features to be enabled/disabled in config.php
    before including this file.  For example:
        $EnableQAMarkup=0;                      #disable Q: and A: tags
        $EnableWikiStyles=1;                    #include default wikistyles
    Each feature has a default setting, if the corresponding $Enable
    variable is not set then you get the default.

    To avoid processing any of the features of this file, set 
        $EnableStdConfig = 0;
    in config.php.
