This is fillit, a project from 42 school.
Just do a make and use it like ./fillit fillit_map
In the includes/fillit.h file, there is some preprocessor variables to pimp the fillit a little bit.
DEBUG: If set to 1, errors will become verbose.TETRI_*: These variables are not working properly, but you can make them work. Actually the fillit is just working with defaults 42's subject values.
