      (description
       "Darwin's @code{cctools} are a set of tools somewhat similar in purpose
to GNU Binutils, but for Mach-O files targeting Darwin.  The suite includes
@command{install_name_tool}, @command{dyldinfo}, and other specialized tools
in addition to standard utilities like @command{ld} and @command{as}.  This
package provides portable versions of the tools.")
