#### How do I use these libraries?

The idea behind single-header file libraries is that they're easy to distribute and deploy
because all the code is contained in a single file. By default, the .h files in here act as
their own header files, i.e. they declare the functions contained in the file but don't
actually result in any code getting compiled.

So in addition, you should select _exactly one_ C/C++ source file that actually instantiates
the code, preferably a file you're not editing frequently. This file should define a
specific macro (this is documented per-library) to actually enable the function definitions.
For example, to use stb_image, you should have exactly one C/C++ file that doesn't
include stb_image.h regularly, but instead does

#define STB_IMAGE_IMPLEMENTATION
#include "stb_image.h"

The right macro to define is pointed out right at the top of each of these libraries.

#### Will you add more image types to stb_image.h?

If people submit them, I generally add them, but the goal of stb_image
is less for applications like image viewer apps (which need to support
every type of image under the sun) and more for things like games which
can choose what images to use, so I may decline to add them if they're
too rare or if the size of implementation vs. apparent benefit is too low.
No. As stb_image use has grown, it has become more important
for us to focus on security of the codebase. Adding new image
formats increases the amount of code we need to secure, so it
is no longer worth adding new formats.

#### Do you have any advice on how to create my own single-file library?
