DESCRIPTION

       The grohtml front end (which consists of a  preprocessor,  pre-grohtml,
       and  a  device driver, post-grohtml) translates the output of GNU troff
       to html.  Users should always invoke grohtml via the groff command with
       a -Thtml option.  If no files are given, grohtml will read the standard
       input.  A filename of - will also cause grohtml to  read  the  standard
       input.  Html output is written to the standard output.  When grohtml is
       run by groff options can be passed to grohtml using groff's -P option.

       grohtml invokes groff twice.  In the first pass,  pictures,  equations,
       and  tables  are  rendered  using the ps device, and in the second pass
       HTML output is generated by the html device.

       grohtml always  writes  output  in  UTF-8  encoding  and  has  built-in
       entities  for  all non-composite unicode characters.  In spite of this,
       groff may issue warnings about unknown special characters if they can't
       be  found  during  the first pass.  Such warnings can be safely ignored
       unless the special characters appear inside a table or equation.

OPTIONS

       -aaa-text-bits
              Number of bits of antialiasing information to be  used  by  text
              when  generating  png images.  The default is 4 but valid values
              are 0, 1, 2, and 4.  Note your version of gs  needs  to  support
              the  -dTextAlphaBits  and -dGraphicAlphaBits options in order to
              exploit antialiasing.  A value of 0 stops grohtml  from  issuing
              antialiasing commands to gs.

       -b     Initialize the background color to white.

       -Ddir  Inform grohtml to place all image files into directory dir.

       -e     This  option should not be directly invoked by the user as it is
              an internal option utilized by groff when -Thtml or  -Txhtml  is
              specified.   It is used by the grohtml preprocessor to determine
              whether eqn should attempt to  produce  MathML  (if  -Txhtml  is
              specified).

       -Fdir  Prepend  directory  dir/devname  to the search path for font and
              device description files;  name  is  the  name  of  the  device,
              usually html.

       -gaa-graphic-bits
              Number  of  bits  of  antialiasing  information  to  be  used by
              graphics when generating png images.  The default is 4 but valid
              values  are  0,  1,  2, and 4.  Note your version of gs needs to
              support the -dTextAlphaBits and  -dGraphicAlphaBits  options  in
              order  to exploit antialiasing.  A value of 0 stops grohtml from
              issuing antialiasing commands to gs.

       -h     Generate section and number headings  by  using  <B>...</B>  and
              increasing  the  font  size,  rather than using the <Hn>...</Hn>
              tags.

       -iresolution
              Select the resolution for all images.  By default  this  is  100
              pixels per inch.  Example: -i200 indicates 200 pixels per inch.

       -Istem Determine   the  image  stem  name.   If  omitted  grohtml  uses
              grohtml-XXX (XXX is the process ID).

       -jfilename
              Inform grohtml to split the html  output  into  multiple  files.
              The filename is the stem and specified section headings (default
              is level one) start a new file, named filename-n.html.

       -l     Turn off the production of automatic section links at the top of
              the document.

       -n     Generate   simple  heading  anchors  whenever  a  section/number
              heading is found.  Without the option the anchor  value  is  the
              textual  heading.   This  can  cause  problems  when  a  heading
              contains a `?' on older versions of  some  browsers  (Netscape).
              This  flag  is  automatically turned on if a heading contains an
              image.

       -overtical-offset
              Specify the vertical offset of images in points.

       -p     Display  page  rendering  progress  to  stderr.   grohtml   only
              displays a page number when an image is required.

       -r     Turn off the automatic header and footer line (html rule).

       -s size
              Set  the  base  point  size of the source file.  Thereafter when
              this point size is used in the source it will correspond to  the
              html base size.  Every increase of two points in the source will
              yield a <big> tag, and conversely when a decrease of two  points
              is seen a <small> tag is emitted.

       -Slevel
              When  splitting  html  output,  split  at  the heading level (or
              higher) defined by level.

       -v     Print the version number.

       -V     Create an XHTML or HTML validator button at the bottom  of  each
              page of the document.

       -xdialect
              Select  HTML  dialect.   Currently, dialect should be either the
              digit 4 or the letter x which indicates whether  grohtml  should
              generate  HTML 4 or XHTML, respectively.  This option should not
              be directly invoked by the user as  it  is  an  internal  option
              utilized by groff when -Thtml or -Txhtml is specified.

       -y     Produce  a  right-justified  groff  signature  at the end of the
              document.  This is  only  generated  if  the  -V  flag  is  also
              specified.

USAGE

       There  are  styles  called  R, I, B, and BI mounted at font positions 1
       to 4.

DEPENDENCIES

       grohtml is dependent upon the png utilities (pnmcut, pnmcrop, pnmtopng)
       and  GhostScript (gs).  pnmtopng (version 2.37.6 or greater) and pnmcut
       from the netpbm package (version 9.16 or greater) will work  also.   It
       is  also  dependent upon psselect from the PSUtils package.  Images are
       generated whenever a table, picture, equation or line is encountered.

FILES

       grohtml uses temporary files.  See the groff(1) man  page  for  details
       where such files are created.

ENVIRONMENT

       GROFF_FONT_PATH
              A  list  of  directories  in  which  to  search  for the devname
              directory in addition to the default  ones.   See  troff(1)  and
              groff_font(5) for more details.

BUGS

       Grohtml has been completely redesigned and rewritten.  It is still beta
       code.
