NMAKE builds only specified targets or, if none is specified, the first target in the makefile. The first makefile target can be a pseudotarget that builds other targets. NMAKE uses makefiles specified with /F; if /F is not specified, it uses the Makefile file in the current directory. If no makefile is specified, it uses inference rules to build command-line targets.
The commandfile text file (or response file) contains command-line input. Other input can precede or follow @commandfile. A path is permitted. In commandfile, line breaks are treated as spaces. Enclose macro definitions in quotation marks if they contain spaces.
