This is a PPWIZARD command line switch.
This switch alters the way "/DependsOn" works.
Normally ppwizard is very strict in its input dependancy checking in that it puts itself and any spelling dictionaries used in the list as well as checking command line switches. This means that when one of these items changes everything gets remade. While the safest option is to leave it on you may wish to turn it off.
Note that this switch controls the building of the dependancy file. Existing dependancy files will need to rebuild at least once under the new setting for everything to work as you wish, for this reason you may wish to delete any existing dependancy files when you change the setting.
