 ## <a name="index-1">1. What is make?</a>
 The `make` utility is an automatic tool capable of deciding which commands can / should be executed. The `make` utility is mostly used to automate the compilation process, preventing manual file-by-file compilation. This utility is used through a special file called `Makefile`.

 There are a few special targets that can be used in a Makefile. These targets are not files but, rather commands that can be executed by the Makefile. Please note that these are not all the targets, but rather only the ones I use the most/are more useful.
 
 - `.SILENT` - Disables the default logging of Make actions in the terminal. If used with prerequisites, only those targets are executed silently.
