     VVii (visual) is a display oriented text editor based on ex(1).  Ex and vvii
     run the same code; it is possible to get to the command mode of ex from
     within vvii and vice-versa.

     VViieeww is the same as ``vi -R'', e.g. run in read-only mode.

     Available options:

     --RR         Read only. Changes to the file may not be written out.

     --ll         Sets options for editing LISP source (options sshhoowwmmaattcchh and
                lliisspp).

     --rr         In the event of an editor or system crash, the --rr option will
                retrieve the last saved version of the specified file, or if
                no file is specified, a list of saved files is printed.

     --tt _t_a_g     If tags are used (see ctags(1))  the editor is postioned at
                _t_a_g.

     --ww_n        The default window size is set to _n.

     ++_c_o_m_m_a_n_d   Enter the file with _c_o_m_m_a_n_d_. Useful for positioning on a
                string or line number.

     The vvii command uses the following environment variables.

     EXINIT      User specified startup values for ex and vvii. Usually speci-
                 fied in the file _~_/_._e_x_r_c

     HOME        Default directory to search for the file _~_/_._e_x_r_c

     SHELL       Shell used for _e_s_c_a_p_e_d commands (with the ex ::!! command).

     TERM        Terminal type used to lookup terminal capabilities from the
                 file _/_u_s_r_/_s_h_a_r_e_/_m_i_s_c_/_t_e_r_m_c_a_p.

     TERMCAP     If set, specifies an alternate termcap file.

BBUUGGSS
     Software tabs using ^^TT work only immediately after the aauuttooiinnddeenntt.

     Left and right shifts on intelligent terminals don't make use of insert
     and delete character operations in the terminal.

     The wwrraappmmaarrggiinn option can be fooled since it looks at output columns when
     blanks are typed.  If a long word passes through the margin and onto the
     next line without a break, then the line won't be broken.

     Insert/delete within a line can be slow if tabs are present on intelli-
     gent terminals, since the terminals need help in doing this correctly.

     Saving text on deletes in the named buffers is somewhat inefficient.

     The ssoouurrccee command does not work when executed as ::ssoouurrccee; there is no
     way to use the ::aappppeenndd, ::cchhaannggee, and ::iinnsseerrtt commands, since it is not
     possible to give more than one line of input to a :: escape.  To use these
     on a ::gglloobbaall you must QQ to ex command mode, execute them, and then reen-
     ter the screen editor with vvii or ooppeenn.

     The vvii command appeared in 3.0BSD.
