								A dictionary of file extensions and associated module loaders.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								## What is it
							 | 
						||
| 
								 | 
							
								This is used by [Liftoff](http://github.com/tkellen/node-liftoff) to automatically require dependencies for configuration files, and by [rechoir](http://github.com/tkellen/node-rechoir) for registering module loaders.

								### extensions

								Map file types to modules which provide a [require.extensions] loader.

								### jsVariants
							 | 
						||
| 
								 | 
							
								Same as above, but only include the extensions which are javascript variants.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								## How to use it
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								Consumers should use the exported `extensions` or `jsVariants` object to determine which module should be loaded for a given extension. If a matching extension is found, consumers should do the following:
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								1. If the value is null, do nothing.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								2. If the value is a string, try to require it.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								3. If the value is an object, try to require the `module` property. If successful, the `register` property (a function) should be called with the module passed as the first argument.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								4. If the value is an array, iterate over it, attempting step #2 or #3 until one of the attempts does not throw.
