Required. * enum | Name of the enum entry. If not set defaults to CMD_{command}. * flags | A set of the flags from below list joined by bitwise or. * func | Name of the function containing the implementation. * * Referenced function should be either non-static one or defined in * ex_docmd.c and be coercible to ex_func_T type from below. * * All keys not described in the above table are reserved for future use. * * 2. Add a "case: CMD_xxx" in the big switch in ex_docmd.c. * 3. Add an entry in the index for Ex commands at ":help ex-cmd-index". * 4. Add documentation in ../doc/xxx.txt.
