       This manual page is not meant to be exhaustive.  The  com-
       plete  documentation  for this version of TeX can be found
       in the info file or manual _W_e_b_2_C_: _A _T_e_X _i_m_p_l_e_m_e_n_t_a_t_i_o_n.

       The ggffttooddvvii program converts a generic font (_g_f) file out-
       put  by, for example, mmff(1), to a device independent (DVI)
       file (that can then be typeset  using  the  same  software
       that  has already been written for TeX). The characters in
       the _g_f file will appear one per page, with labels, titles,
       and  annotations  as  specified  in  Appendix  H (Hardcopy
       Proofs) of _T_h_e _M_e_t_a_f_o_n_t_b_o_o_k.

       ggffttooddvvii uses other fonts in addition to the main _g_f  file.
       A  `gray' font is used to typeset the pixels that actually
       make up the character. (We wouldn't want all the pixels to
       be  simply black, since then labels, key points, and other
       information would be lost.)  A `title' font  is  used  for
       the  information at the top of the page. A `label' font is
       used for the labels on key points of the figure. A `slant'
       font  is  used  to typeset diagonal lines, which otherwise
       have to be simulated using horizontal and vertical  rules.
       The  default  gray, title, and label fonts are _g_r_a_y, _c_m_r_8,
       and _c_m_t_t_1_0, respectively; there is no default slant  font.

       To change the default fonts, you can give ssppeecciiaall commands
       in your Metafont source file, or you can change the  fonts
       online.   An   online   dialog   ensues  if  you  end  the
       _g_f___f_i_l_e___n_a_m_e with a `/'. For example,
         gftodvi cmr10.300gf/
         Special font substitution: grayfont black
         OK; any more? grayfontarea /home/art/don/
         OK; any more? slantfont /home/fonts/slantimagen6
         OK; any more? <RET>
       will  use  _/_h_o_m_e_/_a_r_t_/_d_o_n_/_b_l_a_c_k  as  the  `gray'  font  and
       _/_h_o_m_e_/_f_o_n_t_s_/_s_l_a_n_t_i_m_a_g_e_n_6  as  the  `slant' font (this name
       indicates a font for lines with slope 1/6 at  the  resolu-
       tion of an Imagen printer).

       The  _g_f___f_i_l_e___n_a_m_e  on  the  command line must be complete.
       (The program prompts you for it if  you  don't  give  it.)
       Because  the resolution is part of the extension, it would
       not make sense to append a default extension  as  is  done
       with  TeX  or  DVI-reading  software. The output file name
       defaults to the same root as the _g_f  file,  with  the  _d_v_i
       extension  added. For example, the input file _c_m_r_1_0_._2_6_0_2_g_f
       would become _c_m_r_1_0_._d_v_i.

OOPPTTIIOONNSS
       The argument to --oovveerrffllooww--llaabbeell--ooffffsseett specifies the  dis-
       tance from the right edge of the character bounding box at
       which the overflow equations (if any)  are  typeset.   The
       value  is  given  in  TeX points.  The default is a little
       over two inches.

       Without the --vveerrbboossee option,  ggffttooddvvii  operates  silently.
       With  it, a banner and progress report are printed on _s_t_d_-
       _o_u_t.

EENNVVIIRROONNMMEENNTT
       ggffttooddvvii looks for _g_f___f_i_l_e___n_a_m_e using the environment vari-
       able  GFFONTS.   If  that is not set, it uses the variable
       TEXFONTS. If that is not set, it uses the system  default.

       See tteexx(1) for the details of the searching.
