with an added suffix; a file whose name is just @var{feature} won't be
used.
If loading the file fails to provide @var{feature}, @code{require}
signals an error, @samp{Required feature @var{feature} was not
provided}, unless @var{noerror} is non-@code{nil}.
If @var{noerror} is non-@code{nil}, that suppresses errors from actual
loading of the file. In that case, @code{require} returns @code{nil}
if loading the file fails. Normally, @code{require} returns
@var{feature}.
If loading the file succeeds but does not provide @var{feature},
@code{require} signals an error, @samp{Required feature @var{feature}
was not provided}.
