Project property sheets store project compiler and tool properties that are shared across multiple software projects. Property sheets enable a global repository of compiler and tool settings, so that changes in a global project property sheet will automatically propagate to the project property sheets that inherit from the global project property sheet, or from other project property sheets that inherit from the global project property sheet. Users of project property sheets are able to customize their project property sheet by defining their own compiler and tool properties. Defined compiler and tool properties override or supplement compiler and tool properties found in the global project property sheet.
