Compilation Descriptions 

Use

A compilation description specifies how the module files vcn12.cpp, vcn13.cpp and vcn14.c depend on the include files.

In addition to the dependency of a module file on an include file, a compilation description specifies further properties of the module files that control how they are translated by the development environment.

The compilation description appropriate to a module file is determined and evaluated implicitly using the directory in which the module file to be translated is stored.
