 Like other configuration files in Unix/Linux systems, writing a ''makefile'' (which is also a simple text file) is relatively easy. Any strings following the '#' character are treated as comments. A simple example of a ''makefile'' that can be used to compile a C program from a single 'single.c' source file is shown below.
+//**Note**: This is based on GNU make utility. There are other variation(s) such as the BSD make.//
 <file make makefile>

 It is sometimes very useful to be able to provide information (@input) to the program at command line. This can be made possible by declaring 2 parameters: <code c param.c>
