+This directive is used by some assemblers to place tags in object files.  The
+behavior of this directive varies depending on the target.  When using the
+a.out object file format, @command{@value{AS}} simply accepts the directive for
+source-file compatibility with existing assemblers, but does not emit anything
+for it.  When using COFF, comments are emitted to the @code{.comment} or
+@code{.rdata} section, depending on the target.  When using ELF, comments are
+emitted to the @code{.comment} section.
