/* For now, this is just a collection of includes.

* This is for the purpose of avoid redundant importing of
|
||||
* commonly used includes like stdlib, stdbool or errno,
|
||||
* that are used in almost all files. It really is meant to make
|
||||
* The beginning of reach file more readable.
|
||||
* In the future, I will also use this to define some structs
|
||||
* that are needed in many other places to help juggling
|
||||
* loads of different includes. */
