Description

Activate / deactivate MU library processing

Either copies an MU plugin from the source to the target or removes the MU plugin file from the target Note: WPMU_PLUGIN_DIR may not have been defined if we're invoked from wp-config.php, but ABSPATH should have been. MU plugin files are loaded in ascending alphabetical order. For MU plugin for oik-bwtrace is prefixed with an underscore so that it's loaded very early. The MU plugin for oik-lib is prefixed with two underscores so that it's loaded before oik-bwtrace
