					The <file>GPM</file> unit implements an interface to <file>libgpm</file>, 
 | 
				
			||||||
 | 
					the console program for mouse handling. This unit was created by Peter 
 | 
				
			||||||
 | 
					Vreman, and is only available on linux.
 | 
				
			||||||
 | 
					</p>
 | 
				
			||||||
 | 
					<p>
 | 
				
			||||||
 | 
					When this unit is used, your program is linked to the C libraries, so
 | 
				
			||||||
 | 
					you must take care of the C library version. Also, it will only work with
 | 
				
			||||||
 | 
					version 1.17 or higher of the <file>libgpm</file> library.
