Makefile file format; makefile pseudo target

Makefile contains the target file, dependent files, run the command three parts. 

The basic format of each part, for example, the following:

test: prog.o code.o 

        gcc -a test prog.o code.o

Them, test the first line is the target file . prog.o, code.o is dependent files ;

           Gcc -o test prog.o code.o second line is to run the command .

Throughout the Makefile is such a format.
