DESCRIPTION

       (This manual page was written for  the  Debian  GNU/Linux  distribution
       because  the original program does not have a manual page.  Instead, it
       is documented in detail at the  author's  website;  see  below.  Please
       refer   to   that   documentation  for  more  details  or  up  to  date
       information.)

       This page documents briefly the portmanteau perl script mk4ht, the more
       specific  shell  scripts  httex, htlatex, httexi, and others like them,
       the lower level shell script interface ht, and the commands tex4ht  and
       t4ht  that all these scripts invoke. Together these programs constitute
       TeX4ht; a highly configurable TeX-based authoring system for  producing
       hypertext.

       TeX4ht  interacts  with  TeX-based  applications  through  a style file
       tex4ht.sty and other files which are loaded by this style file, leaving
       the  processing  of  the  source  files to the native TeX compiler. The
       output of the TeX compiler is then post-processed by tex4ht  and  t4ht.
       Consequently,  TeX4ht  can handle most features of TeX-based systems in
       general, and of LaTeX in particular.

       The shell scripts  httex , htlatex and httexi convert TeX (respectively
       LaTeX  and  texinfo)  into  HTML.  Typical  user requirements should be
       satisfied by these scripts which  can  generally  convert  typical  TeX
       source without requiring any modifications.

       To  convert  from a one of the other dialects of TeX (like ConTeXt), or
       to convert into one of the other variants of hypertext (MathML, XML, OO
       and so on), it is recommended that you use the perl script mk4ht.  Most
       common usage of the system can be covered by  the  appropriate  use  of
       this command with its options.

       The shell script  ht is a much more elementary script which is provided
       for more complicated needs.   Its  correct  use  depends  on  a  better
       understanding of the system.

       All these scripts begin with suitable invocations of tex(1) or latex(1)
       or other dialects of TeX as required. The post-processing of  the  .dvi
       output  is  handled  by tex4ht.  Anything that cannot be rendered using
       HTML (or its chosen hypertext variant), such as the creation of  bitmap
       images  or  CSS (Cascade Style Sheet) files is handled by the auxiliary
       program t4ht.  The  method  used  for  generating  the  images  can  be
       configured.

OPTIONS

       The following is only a very brief summary of the main program options.
       For more details of the command-line and configuration options, see the
       HTML documentation (see below).

   Options for httex, htlatex and httexi
       httex, htlatex and httexi are shell scripts that can be used to convert
       a file in the TeX/LaTeX/texinfo format into HTML. This TeX source  file
       should  be  like  any  other TeX source file normally used to produce a
       .dvi file by processing with TeX and friends. The name of such  a  file
       is  the mandatory file argument for each script. This is followed by up
       to three optional arguments (delimited  with  quotation  marks).  These
       arguments, which are not required for typical usage, are as follows:

       1.     The first argument is a list of options for the tex4ht.sty style
              file (used with tex or latex), separated with commas.   See  the
              HTML  documentation  for the list of options available. The .log
              file generated by tex/latex also includes summaries of  some  of
              the  options  available.  If not empty, this argument must start
              with html or xhtml.   Additional  options  could  be  mathml  or
              docbook to indicate appropriate style of output.

       2.     This  argument  is  used to select tagged sections of tex4ht.env
              that specifies the font files (*.htf) to use.  This  corresponds
              to  the  -c  option  for  the command tex4ht as explained below.
              Examples include unicode or mozilla.

       3.     This argument lists options for the t4ht  program  as  explained
              below.

       See the HTML documentation for more details and examples.

       Similar  scripts  are  available within the directory /usr/share/tex4ht
       for generating other kinds of hypertext output. It is also possible  to
       use the perl script mk4ht as explained below.

   Options for mk4ht
       mk4ht  is  a  perl  script that can be used to convert TeX source files
       from numerous dialects of TeX into different hypertext  variants.  This
       script  takes  two  mandatory arguments: the name of the command to run
       and the file to run it  on.  Each  possible  command  is  of  the  form
       "<variant><dialect>":  so  for  example xhmlatex denotes a LaTeX source
       that needs to  be  converted  to  XHTML  with  MathML  extensions.  The
       possible  names  for  commands  can  be  found by listing the directory
       /usr/share/tex4ht.  The three optional arguments to mk4ht are identical
       to  those  outlined  above for httex, htlatex and httexi.  In fact, the
       command htlatex foo is identical to mk4ht htlatex foo except  that  the
       former  is shorter to type! However, mk4ht can be configured to shorten
       the command line as follows.

       Each user can create the configuration file mk4ht.cfg or .mk4ht in  the
       home or working directory to configure commonly used options for mk4ht;
       in addition options to clean up temporary files can also  be  added  to
       this   configuration  file.  Running  the  command  mk4ht  without  any
       arguments will summarise the use of this user configuration file.

   Options for ht
       ht is a small shell script that is used to run the tex4ht programs.  It
       has two compulsory arguments, as follows:

       1.     The TeX command name to run, usually either tex or latex.

       2.     The input file name (with or without extension).

       It may take any additional options, which will be passed on to the call
       to t4ht.

   General directory/file search options
       Several of the options detailed below relate to setting directory paths
       to  find particular kinds of files.  Note the following when specifying
       directories for the programs:

       1.     There must be no space between the option letter  (eg,  -t)  and
              the directory/file name.

       2.     The  directory  name must end with a trailing slash (/, or /!  -
              see below).

       3.     You can add an exclamation mark (!)  to the end of the directory
              name, to enable sub-directory searching.

       4.     Only  one  directory  can  be  specified  at  a time.  To search
              multiple directories, either  use  the  sub-directory  searching
              facility  or  repeat  the option.  (The directory search options
              can be repeated as often as required.)

       5.     When compiled with kpathsea (as  in  the  Debian  package),  the
              path-searching  is  in part taken over by kpathsea.  On a Debian
              system  see   /usr/share/doc/tex4ht/README.kpathsea   for   more
              information on path-searching in a kpathsea-enabled tex4ht.

       As  well  as  command-line  options,  most  of  these  options can (and
       normally should) be set in  the  configuration  file  tex4ht.env.   The
       format  within  this file is similar, but without using a hyphen before
       the option letter. See the HTML documentation for more details  on  the
       configuration  options available. The file tex4ht.env can be superseded
       on a per-directory and/or a per-user basis as  explained  in  the  HTML
       documentation.        On        a        Debian        system       see
       /usr/share/doc/tex4ht/README.Debian as well.

   Options for tex4ht
       -ctag-name
              Certain lines within the tex4ht.env configuration  file  can  be
              marked  with  tags.   These lines (typically htf-font-dir search
              lines)  will  be  omitted  unless  specifically   requested   by
              specifying  the  tag  name  on  the tex4ht command line.  If not
              used, a command-line option of -cdefault is assumed.   (See  the
              supplied tex4ht.env file for examples of tagged sections.)

       -eenv-file
              Specify address of the tex4ht configuration file tex4ht.env.

       -gbitmap-file-ext
              Set the extension of bitmap images to bitmap-file-ext instead of
              the default .png.  Note that the extension should begin  with  a
              dot  (.).   Note  also  that  this  option  only  affects images
              generated  automatically  for  symbol  fonts,  and  not   images
              generated with the \Picture macro of tex4ht.

       -he    Trace errors and warnings (produces verbose output).

       -hg    Trace groups

       -hs    Trace \specials.

       -hV    Trace search path for tex4ht.env configuration file

       -hF    Trace search path for .htf font files

       -hv    Dump  contents  of found tex4ht.env configuration file to stderr
              (for debugging)

       -hf    Dump contents of each  .htf  font  file  found  to  stderr  (for
              debugging)

       -ihtf-font-dir
              Set  directory  for HTF font files (used by tex4ht) to htf-font-
              dir.

       -lbookkeeping-file
              Specify name of the file listing cache used to speed up filename
              lookups (ignored if compiled with kpathsea support)

       -Pfilter
              Restrict  system  calls requested in the source (La)TeX files to
              utilities whose names have filter as a  prefix.   Use  a  single
              asterisk as filter to allow any system calls.

       -ttfm-font-dir
              Set  directory  for  TFM  font files to tfm-font-dir (ignored if
              compiled with kpathsea support).

       -u10   Use base 10 encoding for unicode characters.

       -utf8  Use utf-8 encoding for unicode characters.

       -xs    Use 8.3 (MSDOS style) file names for the generated PNG files.

   Options for t4ht
       -ctag-name
              Certain lines within the tex4ht.env configuration  file  can  be
              marked  with  tags.   These  lines  (typically scripts for post-
              processing files) will be omitted unless specifically  requested
              by  specifying  the tag name on the tex4ht command line.  If not
              used, a command-line option of -cdefault is assumed.   (See  the
              supplied tex4ht.env file for examples of tagged sections.)

       -dout-dir
              Output  files  to  directory  out-dir, instead of to the current
              directory.

       -eenv-file
              Specify address of the tex4ht configuration file tex4ht.env.

       -i     Generate verbose debugging output.

       -mmode Create any new output files with access  mode  as  indicated  by
              mode.   The  mode  should  be  a  numeric  mode,  as used by the
              chmod(1) command.

       -Mmode As -m but change all mode of all output files (including  reused
              bitmaps).

       -p     Do  not  convert pictures (ie, images generated with macros like
              \Picture,  not  characters  in  symbol  fonts   that   will   be
              automatically converted into a graphic file).

       -r     Do  not  resuse  existing  bitmaps  of glyphs (for characters in
              symbol fonts etc), but instead generate all bitmaps anew.

       -Sfilter
              Restrict system calls requested in the source (La)TeX  files  to
              utilities  whose  names  have  filter as a prefix.  Use a single
              asterisk as filter to allow any system calls.

       -Xfield-content
              Scripts  for  post-processing  of  files  can  be  specified  in
              tex4ht.env.   If these scripts refer to a field %%3, content for
              that field can be set with this command-line option.

       -.field-content
              Scripts for post-processing of groups of files with a particular
              extension  can  be  specified  in  tex4ht.env.  If these scripts
              refer to a field %%2, content for that field  can  be  set  with
              this command-line option.
