Abstract:
Microsoft Editor extension definitions.
#ifndef SHIP
NOTES: THIS FILE IS SHIPPED WITH THE PRODUCT!!!!
BE VERY carefull what gets put into this file. Technically, if it is NOT required for extension writers, it does NOT belong here.
1) This note, the file history and all code within "#ifndef SHIP" and "#if defined EDITOR" conditionals should be REMOVED before shipping.
