           groff -mwww [ options ] file ...


           This  manual  page describes the GNU -mwww macro package, which is part
           of the groff document formatting system.  The manual  page  is  very  a
           basic  guide,  and the html device driver (grohtml) has been completely
           rewritten but still remains as in an alpha state.  It has been included
           into the distribution so that a lot of people have a chance to test it.
           Note that this macro file will be automatically called (via the troffrc
           file) if you use -Thtml.
           To  see  the hyperlinks in action, please format this man page with the
           grohtml device.
           Here is a summary of the functions found in this macro set.
           .HX                 automatic heading level cut off;
                               $1 point for sections/headers
           .BCL                specify colours on a web page
           .BGIMG              specify background image
           .URL                create a url using two parameters
           .FTP                create an ftp reference
           .MTO                create a html email address
           .FTP                create an ftp reference
           .TAG                generate an html name
           .IMG                include an image file
           .PIMG               include png image
           .MPIMG              place png on the margin and
                               wrap text around it
           .HnS                begin heading
           .HnE                end heading
           .LK                 emit automatically collected links.
           .HR                 produce a horizontal rule
           .NHR                suppress automatic generation of rules.
           .HTL                only generate HTML title
           .ULS                unorder list begin
           .ULE                unorder list end
           .LI                 insert a list item
           .DC                 generate a drop capital
           .HTML               pass an html raw request to the
                               device driver
           Output of the pic, eqn, refer, and tbl preprocessors is  acceptable  as


           HX     Specify  the  cut  off  depth when generating links from section
                  headings.  For example, a parameter of 2 would cause grohtml  to
                  generate  a list of links for .NH 1 and .NH 2 but not for .NH 3.
                  and the third is optional stuff to be printed immediately after-
                  wards.   Hyphenation  is disabled while printing the actual URL;
                  explicit breakpoints should be  inserted  with  the  \:  escape.
                  Here is how to encode foo <>:
                         .URL http://\:foo.\:org/ foo :
                  If  this  is  processed by a device other than -Thtml it appears
                         foo <>:
                  The URL macro can be of any type; for example we  can  reference
                  Eric Raymond's pic guide <pic.html> by:
                         .URL pic.html "Eric Raymond's pic guide"
           MTO    Generate  an email html reference.  The first argument is manda-
                  tory as the email address.  The optional second argument is  the
                  text  you see in your browser, and an optional third argument is
                  stuff printed immediately afterwards.  Hyphenation  is  disabled
                  while  printing the actual email address.  For example, Joe User
                  <> was achieved by the following macro:
                         .MTO "Joe User"
                  Note that all the URLs actually are treated as consuming no tex-
                  tual space in groff.  This could be considered as a bug since it
                  causes some problems.  To circumvent this,  www.tmac  inserts  a
                  zero-width  character which expands to a harmless space (only if
                  run with -Thtml).
           FTP    indicates that data can be obtained via ftp.  The first argument
                  is  the  url  and the second is the browser text.  A third argu-
                  ment, similar to the macros above, is intended for stuff printed
                  immediately  afterwards.  The second and the third parameter are
                  optional.  Hyphenation is disabled  while  printing  the  actual
                  URL.   As  an  example,  here the location of the GNU ftp server
                  <>.  The macro example above was specified by:
                         .FTP ftp://\ "GNU ftp server" .
           TAG    Generates  an html name tag from its argument.  This can then be
                  referenced using the URL <#URL> macro.  As you can see, you must
                  precede the tag name with # since it is a local reference.  This
                  link was achieved via placing  a  TAG  in  the  URL  description
                  above; the source looks like this:
                         .B URL
                         .TAG URL
                  ing with postscript and html devices also since it can automati-
                  cally convert the image into the EPS format, using the following
                  programs of the netpbm package: pngtopnm, pnmcrop, and  pnmtops.
                  If  the  document isn't processed with -Thtml it is necessary to
                  use the -U option of groff.
           MPIMG  Place a PNG image on the margin and wrap text  around  it.   The
                  first parameter is the alignment: left or right (-L or -R).  The
                  second argument is the filename.  The optional third and  fourth
                  arguments  are  the width and height.  If the width is absent it
                  defaults to 1 inch.  If the height is absent it defaults to  the
           HnS    Begin  heading.   The  heading  level  is specified by the first
                  parameter.  Use this macro of your headings contain URLs.  Exam-
                         .HnS 1
                         GNU Troff
                         .URL (Groff)
                         --- a
                         .URL GNU
                         Hosted by
                         .URL FFII .
           HnE    End heading.
           LK     Force grohtml to place the automatically generated links at this
                  position.  If this manual page has been  processed  with  -Thtml
                  those links can be seen right here.


           By  default  grohtml generates links to all section headings and places
           these at the top of the html document. (See LINKS <#LK> for details  of
           how to switch this off or alter the position).
           HR     Generate a full-width horizontal rule.
           NHR    Suppress  generation  of  the top and bottom rules which grohtml
                  emits by default.
           HTL    Generate an HTML title only.  This differs from the TL macro  of
                  the  ms  macro package which generates both an HTML title and an
                  H1 heading.  Use it to provide an HTML title  as  search  engine
                  fodder but a graphic title in the document.
           HTML   All  text after this macro is treated as raw html.  If the docu-
                  ment is processed without -Thtml  then  the  macro  is  ignored.


           tbl information is currently rendered as a PNG image.
