This is a collection of small graphical demos, and a library
to display them using openGL.

Installation:
-------------
- Edit `config.mk`
- `make`
- `make install`

Requirements
------------
- A C compiler and linker (gcc, tcc, pcc)
- A unix system
- SDL 2, and openGL

Parameters
----------
`CC`        : C compiler command (`gcc`)
`LD`        : Linker command (`$CC`)
`CFLAGS`    : C compiler options (`-Wall -Werror`)
`LDFLAGS`   : Linker options (`-static`)
`PREFIX`    : Prefix for installation files (`/usr/local`)
`MANPREFIX` : Location of manpage directory (`$PREFIX/man`)
'GFXLIB'    : Backend graphics library (`SDL2`)

The author recommends the use of static linking and
a small libc, such as musl, dietlibc, or uclibc.
