+@cindex two-byte integer
+@cindex integer, 2-byte
+
+This directive expects zero or more expressions, separated by commas.  If there
+are no expressions then the directive does nothing.  Otherwise each expression
+is evaluated in turn and placed in the next two bytes of the current output
+section, using the endian model of the target.  If an expression will not fit
+in two bytes, a warning message is displayed and the least significant two
+bytes of the expression's value are used.  If an expression cannot be evaluated
+at assembly time then relocations will be generated in order to compute the
+value at link time.  
+
+This directive does not apply any alignment before or after inserting the
+values.  As a result of this, if relocations are generated, they may be
+different from those used for inserting values with a guaranteed alignment.
+
+This directive is only available for ELF targets,
