+  This is a replacement to the file function that returns nothing
+  if the file specified cannot be found instead of erroring out.
+
+  The argument to this function should be a `<MODULE NAME>/<FILE>`
+  reference, which will load `<FILE>` from a module's `files`
+  directory. (For example, the reference `mysql/mysqltuner.pl` will load the
+  file `<MODULES DIRECTORY>/mysql/files/mysqltuner.pl`.)
+
+  This function can also accept:
+
+  * An absolute path, which can load a file from anywhere on disk.
+  * Multiple arguments, which will return the contents of the **first** file
+  found, skipping any files that don't exist.
