								it is often useful to mark sections that should not be eliminated. 
							 | 
						||
| 
								 | 
							
								This is accomplished by surrounding an input section's wildcard entry
							 | 
						||
| 
								 | 
							
								with <code>KEEP()</code>, as in <code>KEEP(*(.init))</code> or
							 | 
						||
|
