* There are 2 ways to perform OK for CDT property pages.
* 1st (default):
* All pages use the same editable copy of ICProjectDescription.
* When OK occurs, this object is simply set.
*
* 2nd:
* When OK occurs, each page must copy its data to new instance
* of ICProjectDescription, like it occurs during Apply event.
* It allows to avoid collisions with other property pages,
* which do not share ICProjectDescription instance.
* But some changes may be saved wrong if they are affected
* by data from another property pages (Discovery options etc).
* To enable 2nd mode, just create the following file:
* <workspace>/.metadata/.plugins/org.eclipse.cdt.ui/apply_mode
