 Compilation will yield an executable named 'factor' on Unix,

+* Libraries needed for compilation
+
+For X11 support, you need recent development libraries for libc, Freetype,
+X11, OpenGL and GLUT. On a Debian-derived Linux distribution (like Ubuntu),
+you can use the line
+
+sudo apt-get install libc6-dev libfreetype6-dev libx11-dev glutg3-dev
