+FUNCTION
+	bfd_simple_relocate_secton
+
+SYNOPSIS
+	bfd_byte *bfd_simple_get_relocated_section_contents (bfd *abfd, asection *sec, bfd_byte *outbuf);
+
+DESCRIPTION
+	Returns the relocated contents of section @var{sec}.  Only symbols
+	from @var{abfd} and the output offsets assigned to sections in
+	@var{abfd} are used.  The result will be stored at @var{outbuf}
+	or allocated with @code{bfd_malloc} if @var{outbuf} is @code{NULL}.
+
+	Generally all sections in @var{abfd} should have their
+	@code{output_section} pointing back to the original section.
+
+	Returns @code{NULL} on a fatal error; ignores errors applying
+	particular relocations.
