// jdehmel@outlook.com, github.com/jorbDehmel

// Full installation command for graphing library:
// gh repo clone jorbDehmel/jgraph && cd jgraph/jgraph && make && cd ../..

// Add this to compilation command:
// `sdl2-config --cflags --libs` -lSDL2_ttf

// If you get the error 'Cannot open source file "begin_code.h"', don't worry,
// it doesn't matter. (It's a bug in a dependancy library)
