Used when one file is dependent on many files to make sure that the target is younger than all its sources. Allows for an easy test of the form:

if (fileOutOfDate($target, $source1,$source2,$source3))

as in 'make' to decide whether the target needs to be updated from its sources.

Returns the first out of date source file to make debugging easier, or undef if no files are out of date.
