Files - makefile
     A makefile is a set of instructions for creating and assembling
     compiled objects into a complete application.  Opening
     the makefile by double clicking with the mouse button
     number one or by executing the File Menu Open option
     loads the editor with the makefile as a parameter.  The
     Actions Menu make option will run the make interpreter with
     the makefile as a parameter. The interpreter is loaded with
     the -f option.
