+The @var{archives} should be a list of archive files.  They may be
+either explicit file names, or @samp{-l} options.
+
+The specified archives are searched repeatedly until no new undefined
+references are created.  Normally, an archive is searched only once in
+the order that it is specified on the command line.  If a symbol in that
+archive is needed to resolve an undefined symbol referred to by an
+object in an archive that appears later on the command line, the linker
+would not be able to resolve that reference.  By grouping the archives,
+they all be searched repeatedly until all possible references are
+resolved.
+
+Using this option has a significant performance cost.  It is best to use
+it only when there are unavoidable circular references between two or
+more archives.
