+\&\s-1GNU\s0 \fBar\fR can optionally create a \fIthin\fR archive,
+which contains a symbol index and references to the original copies
+of the member files of the archives. Such an archive is useful
+for building libraries for use within a local build, where the
+relocatable objects are expected to remain available, and copying the
+contents of each object would only waste time and space. Thin archives
+are also \fIflattened\fR, so that adding one or more archives to a
+thin archive will add the elements of the nested archive individually.
+The paths to the elements of the archive are stored relative to the
+archive itself.
