		description
			Cpp is the GNU C-Compatible Compiler Preprocessor.
			Cpp is a macro processor which is used automatically
			by the C compiler to transform your program before actual
			compilation. It is called a macro processor because it allows
			you to define macros, abbreviations for longer
			constructs.

			The C preprocessor provides four separate functionalities: the
			inclusion of header files (files of declarations that can be
			substituted into your program); macro expansion (you can define macros,
			and the C preprocessor will replace the macros with their definitions
			throughout the program); conditional compilation (using special
			preprocessing directives, you can include or exclude parts of the
			program according to various conditions); and line control (if you use
			a program to combine or rearrange source files into an intermediate
			file which is then compiled, you can use line control to inform the
			compiler about where each source line originated).

			You should install this package if you are a C programmer and you use
			macros.
