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
$EnableDefaultWikiStyles=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;
