-Delete numbers on the table by moving the pointer.
-
-That's all you need to know.
-
-# How to compile
-
-Current version requires ncures (checkout the no-ncurses branch with
-`git checkout no-ncurses`
-if you don't want it).
-
-Add the path to your LD_LIBRARY_PATH and then compile with the flag -lncurses
-
-ubuntu example:
-
-(as root)
-apt-get install ncurses-dev
-
-(compile)
-`gcc ./Roofus.c -o roofus -lncurses`
