       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
       different 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:

       · the ISO character entities for SGML

       · James Clark’s DSSSL  engine,  jade,  or  an  equivalent  parser  like

       · the DocBook DTD from the OASIS consortium

       · Norman  Walsh’s  DocBook  modular  style sheets (or some other set of
         DSSSL style sheets)

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

       · A perl interpreter (for backends that use perl)

       · SGMLSpm from CPAN (for backends that use sgmls)

       · 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
       convert 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/docbook.dsl  (depending on the backend’s type: html
                     or print).

          -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
                     docbook2man. 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

              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
              DocBook  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
              standard catalogs list is determined like this:

              · if  the  centralized  catalog  exists,  then   use   it.   The
                centralized  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 /etc/sgml/

              · Otherwise,  take  all  the  files  named  catalog   from   the
                subdirectories   of   the   SGML   base   directory   (usually
       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
              "identificator"  is equal to the target’s name). A common use of
              this mechanism 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
              docbook     frontend     returns     ./docbook.dsl#html      (or
              ./docbook.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

              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,
              entities,    etc   are   installed.   The   default   value   is

          -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
              generating  HTML,  because  the output can be split into several
              files. This option overrides the setting that may be done in the
              style sheets.

          -i section | --include section
              Declare  a  SGML  marked  section  as  "include".  A SGML marked
              section 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.
              Warning types that start with "no-"  disable  the  corresponding
              warnings, 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.
