NAME
     vlp - Format Lisp programs to be printed with nroff, vtroff,
     or troff

SYNOPSIS
     vlp [ -p _p_o_i_n_t_s_i_z_e ] [ -d ] [ -f ] [ -l ] [ -v ] [ -T _t_i_t_l_e_1
     ] file1 [ -T _t_i_t_l_e_2 ] file2 ...

DESCRIPTION
     _V_l_p formats the named files so that they can be run through
     nroff, vtroff, or troff to produce listings that line-up and
     are attractive.  The first non-blank character of each line
     is lined-up vertically, as in the source file.  Comments
     (text beginning with a semicolon) are printed in italics.
     Each function's name is printed in bold face next to the
     function.  This format makes Lisp code look attractive when
     it is printed with a variable width font.

     Normally, _v_l_p works as a filter and sends its output to the
     standard output.  However, the -v switch pipes the output
     directly to vtroff.  If no files are specified, then _v_l_p
     reads from the standard input.

     The following options are available:

     -p   The -p switch changes the size of the text from its
          default value of 8 points to one of 6, 8, 10, or 12
          points.  Once set, the point size is used for all sub-
          sequent files.  This point size does not apply to
          embedded text (see -_f below).

     -d   The -d switch puts _v_l_p into debugging mode.

     -f   _V_l_p has a filtered mode in which all lines are passed
          unmodified, except those lines between the directives
          .Ls and .Le.  This mode can be used to format Lisp code
          that is embedded in a document.  The directive .Ls
          takes an optional argument that gives the point size
          for the embedded code.  If not size is specified, the
          size of the surrounding text is used.

     -l   The -l switch prevents _v_l_p from placing labels next to
          functions.  This switch is useful for embedded Lisp
          code, where the labels would be distracting.

     -v   This switch cause _v_l_p to send its output to vtroff
          rather than the standard output.

     -T   A title to be printed on each page may be specified by
          using the -T switch.  The -T switch applies only to the
          next file name given.  Titles are not printed for
          embedded text (see -f, above).  This switch may not be

BUGS
     _v_l_p transforms \ into \\ so that it will be printed out.
     Hence, troff commands cannot be embedded in Lisp code.
