       The  jw  shell  script  allows to convert a DocBook file (or some other
       SGML-based format) to other formats (including HTML, RTF, PS  and  PDF)
       with  an easy-to-understand syntax. It hides most of Jade's or OpenJade
       complexity and adds comfortable features.

       Other scripts like docbook2html, docbook2rtf or docbook2ps provide dif-
       ferent ways of calling jw that might be easier to remember.

       For the moment, jw does not handle XML, but only SGML.

       This  utility  assumes that several other components are installed. The
       list includes:

       o the ISO character entities for SGML

       o James Clark's DSSSL engine, jade, or an equivalent parser like  Open-

       o the DocBook DTD from the OASIS consortium

       o Norman  Walsh's  DocBook  modular  style sheets (or some other set of
         DSSSL style sheets)

       o Sebastian Rahtz's jadetex set of TeX macros for  jade  (for  backends
         intended to "printing" formats like PDF, RTF or PostScript)

       o A perl interpreter (for backends that use perl)

       o SGMLSpm from CPAN (for backends that use sgmls)

       o Lynx HTML browser (for the txt backend)

       The jw script is basically called like this:

       jw mydoc.sgml

       where mydoc.sgml is a SGML file.

       The  command  line above uses default options: it converts from DocBook
       (the default frontend) to HTML (the default backend), does not put  the
       result  in  a  subdirectory  (unless  specified  otherwise in the style
       sheets), etc.

       In this example, the "mydoc" file name as well as the ".sgml" extension
       can  be  replaced by anything else. Current extensions for SGML DocBook
       files include ".sgml", ".sgm", ".docbook",  and  ".db".  The  processed
       file mydoc.sgml can be in any other directory than the current one.

       Here  we have chosen to generate HTML output. In fact we can use any of
       the backends stored in the backends/ subdirectory of the  DocBook-utils
       distribution  directory (usually /usr/share/docbook-utils).  Similarly,
       you can use any frontend defined in the frontends/ subdirectory to con-
       vert from another input format.

       This  sample command creates one or many HTML files with arbitrary file
       names in the current directory. This default behavior  can  be  changed
       through command line options and/or customization style sheets.

       The following options apply to the conversion script:

          -f frontend | --frontend frontend
              Allows  to  specify  another frontend than default docbook.  The
              list of currently available frontends is:

                     Converts docbook with Norman Walsh's style  sheets.  This
                     frontend  searches in the subdirectories of the base SGML
                     directory for a file named html/docbook.dsl or print/doc-
                     book.dsl  (depending  on  the  backend's  type:  html  or

          -b backend | --backend backend
              Allows to specify another backend than default HTML. The list of
              currently available backends is:

              dvi    Converts  to  DVI  (DeVice  Independant files) by calling
                     Jade or OpenJade.

              html   Converts to HTML (HyperText Markup Language)  by  calling
                     Jade or OpenJade.

              man    Converts a refentry to a Unix manual page by calling doc-
                     book2man. Does not work with other  SGML  document  types
                     than DocBook.

              pdf    Converts  to  PDF  (Portable  Document Format) by calling
                     Jade or OpenJade.

              ps     Converts to PostScript by calling Jade or OpenJade.

              rtf    Converts to RTF (Rich Text Format)  by  calling  Jade  or
                     OpenJade. The resulting file can then be inported into MS
                     Word or one of its Linux replacement programs.

              tex    Converts to TeX by calling Jade or OpenJade.

              texi   Converts to GNU TeXinfo pages  by  calling  docbook2texi.
                     Does  not  work  with other SGML document types than Doc-

              txt    Converts to a bare text file by calling Jade or OpenJade,
                     then Lynx.

          -c file | --cat file
              Allows  to  use  an extra SGML Open Catalog that will list other
              files like customization style sheets, adaptations to  the  Doc-
              Book  Document Type Definition, special character entities, etc.
              This catalog is added to the list of catalogs determined by  the
              script (see option --nostd below)

          -n | --nostd
              Do  not use the standard SGML Open Catalogs. Normally, the stan-
              dard catalogs list is determined like this:

              o if the centralized catalog exists, then use it.  The  central-
                ized catalog is a list of all catalogs that might be necessary
                that usually resides in /etc/sgml. Its name is provided by the
                frontend,   for   example   the   docbook   frontend   returns

              o Otherwise, take all the files named catalog from the subdirec-
                tories of the SGML base directory (usually /usr/share/sgml).
       This  option is useful in conjunction with the --cat option to use only
       the catalogs that are specified on the command line.

          -d file|default|none | --dsl file|default|none
              Allows to use a customized style sheet instead  of  the  default

              A  "target" starting with a hash mark "#" can be appended to the
              file name. As a result, only the corresponding part of the style
              sheet  is executed (the "style specification" whose "identifica-
              tor" is equal to the target's name). A common use of this mecha-
              nism  is  to  define "#html" and "#print" targets to trigger the
              corresponding part  of a replacement style sheet which is common
              for both HTML and printout conversion.

              By  replacing  the  file  name with "default", the default style
              sheet provided with the frontend is used. For example, the  doc-
              book    frontend    returns    ./docbook.dsl#html   (or   ./doc-
              book.dsl#print) in the SGML base directory.

              By replacing the file name with  "none",  no  replacement  style
              sheet is used, not even the default style sheet. The style sheet
              which is used is also determined by the frontend.  For  example,
              the docbook frontend returns Norman Walsh's html/docbook.dsl (or
              print/docbook.dsl) found somewhere below the  SGML  base  direc-

              If no --dsl option is specified, then "--dsl default" is used.

          -l file | --dcl file
              Allows  to  use  a  customized  SGML  declaration instead of the
              default one. The file name of the default  SGML  declaration  is
              not  set  for SGML files, and is set to xml.dcl in the SGML base
              directory for XML files.

          -s path | --sgmlbase path
              Allows to use another location for the SGML base directory. This
              is  the directory below which all SGML DTDs, style sheets, enti-
              ties, etc are installed. The default value is /usr/share/sgml.

          -p program | --parser program
              Specify the parser to use (Jade  or  OpenJade)  if  several  are
              installed.  If  this  option  is not specified, the script first
              tries to use Jade, then it tries OpenJade.

          -o directory | --output directory
              Set output directory where  all  the  resulting  files  will  be
              stored. If the style sheets define a subdirectory where to store
              the resulting files too, the subdirectory defined by  the  style
              sheets  will  be  placed  below the subdirectory defined by this

          -V variable=[value]
              Set a variable (to a value, if one is specified).

          -u | --nochunks
              Output only one big file. This option is useful only when gener-
              ating  HTML, because the output can be split into several files.
              This option overrides the setting that may be done in the  style

          -i section | --include section
              Declare  a  SGML marked section as "include". A SGML marked sec-
              tion is a kind of conditional part  of  a  document.  If  it  is
              declared "ignore", it will be left ignored, otherwise it will be
              processed. An example of such a marked section would be:

                   <DOCTYPE mydoc [
                     <!ENTITY % confidential "ignore">
                     <![ %confidential [ Some confidential text... ]]>

          -w type|list | --warning type|list
              Enables or disables the display  of  given  types  of  warnings.
              Several  -w options might be entered on the command line.  Warn-
              ing types that start with "no-" disable the corresponding  warn-
              ings, the other types enable them.

              If  the  warning  type  is  replaced with "list", then a list of
              allowed warning types is displayed.

          -e type|list | --error type|list
              Disables given types of errors.  Several  -e  options  might  be
              entered on the command line.  All error types start with "no-".

              If  the  error  type  is  replaced  with  "list", then a list of
              allowed error types is displayed.

          -h | --help
              Print a short help message and exit

          -v | --version
              Print the version identifier and exit

              Centralized SGML open catalog. This  file  name  might  vary  if
              another frontend than docbook is used.
