 The internal headers are only used while compiling the library,

-the external headers (gl.h, zfeatures.h, zbuffer.h) are requires to use the library.

+the external headers (gl.h, zfeatures.h, zbuffer.h) are required to use the library.

 You CAN compile the library along with your final program into a single compilation unit without separating out the library.

 Doing so is the most likely compiling method for embedded platforms and how I got TinyGL running on the 3DS.

+The codebase uses very simple compiler flags to compile- in fact it will compile if you just compile all c files together

+

+in the src/ directory.

+

+You can compile the code yourself without makefiles using these directives:

+```

+# inside the src directory

+gcc -Wno-uninitialized -O3 -c *.c 

+ar rcs libTinyGL.a *.o

+# the library is now compiled

+cp libTinyGL.a ../lib

+cd ..

+cd SDL_Examples/

+# build the menu demo

+gcc -O3 menu.c -o menu -lSDL ../lib/libTinyGL.a -lm

+# gears

+gcc -O3 gears.c -o gears -lSDL ../lib/libTinyGL.a -lm

 ```c

 //First you have to include

 //(Note that you must either link against libTinyGL.a or compile it in the same compilation unit as your program)
