       Allegro game programming library.

       Example exflame

DESCRIPTION
       This program demonstrates how to write directly to video memory.  It
       implements a simple fire effect, first by calling getpixel() and
       putpixel(), then by accessing video memory directly a byte at a time,
       and finally using block memory copy operations.
