DESCRIPTION

13       The queens program solves the n-queens problem (where, in this program,
14       N  is between 5 and 10 queens) using a straightforward backtracking al‐
15       gorithm.  The problem is: how may one place N queens on an  NxN  chess‐
16       board such that no queen can attack a sister?
17

BUGS

45       It's not unknown for this and other OpenGL hacks to fail under hardware
46       accelaration (UtahGLX) and take the X server with them.  Texture images
47       must be 16x16 or 32x32 or 64x64 etc.
