=head1 DESCRIPTION
This utility takes a list of libraries in the form C<-llib1 -llib2
--llib3> and prints out lines suitable for inclusion in an extension
+-llib3> and returns lines suitable for inclusion in an extension
Makefile. Extra library paths may be included with the form
C<-L/another/path> this will affect the searches for all subsequent
libraries.
-It returns an array of four scalar values: EXTRALIBS, BSLOADLIBS,
-LDLOADLIBS, and LD_RUN_PATH. Some of these don't mean anything
-on VMS and Win32. See the details about those platform specifics
-below.
+It returns an array of four or five scalar values: EXTRALIBS,
+BSLOADLIBS, LDLOADLIBS, LD_RUN_PATH, and, optionally, a reference to
+the array of the filenames of actual libraries. Some of these don't
+mean anything unless on Unix. See the details about those platform
+specifics below. The list of the filenames is returned only if
+$need_names argument is true.
Dependent libraries can be linked in one of three ways:
