+The GNU @code{copy} utility copies the contents of an object file to
+another. @code{copy} uses the GNU BFD Library to read and write the
+object files. It can write the destination object file in a format
+different from that of the source object file. The exact behavior of
+@code{copy} is controlled by command-line options.
+
+@code{copy} creates temporary files to do its translations and
+deletes them afterward. @code{copy} uses BFD to do all its
+translation work; it knows about all the formats BFD knows about, and
+thus is able to recognize most formats without being told explicitly.
