This AtoMorph-GUI implementation is deprecated because it uses
an older version of the AtoMorph Library. The latter has to be
compiled using the `deprecated` build target.
AtoMorph-GUI requires Allegro5.1 installed on your system.
Build instructions:
Run make in this folder.
Edit the Makefile if needed.
Alternative build instructions:
Use CodeBlocks and open AtoMorph-GUI.cbp.
