NAME

       dwww - access documentation via WWW

SYNOPSIS

       http://localhost/dwww/index.html

DESCRIPTION

       A  typical  Linux  system  has  documentation  in  many formats (manual pages, Info files,
       READMEs, and so on).  dwww makes  it  possible  to  access  all  of  these  via  the  same
       interface, a WWW browser.  This makes it easier to use the documentation.

       dwww consists of several programs:

       cgi-bin/dwww
              Run by the WWW server when user requests document via dwww.  Parses the request and
              runs dwww-convert(8) or dwww-find(8) with suitable  arguments.   Installed  in  the
              server's cgi-bin directory.

       dwww-convert(8)
              Converts any document to HTML.

       dwww-format-man(8)
              Auxiliary program to convert man pages or text files to HTML.

       dwww-find(8)
              Searches for documentation.

       dwww-quickfind(8)
              Used by dwww-find(8) to quickly find which package a program belongs to.

       dwww-cache(8)
              Manages the cache of converted documents.

       dwww-refresh-cache(8)
              Cleans outdated documents from the cache.

       dwww-build(8)
              Builds  static  lists  of  manual pages.  Needs to be re-run whenever documents are
              installed or removed.  (In default configuration is called by the dwww  daily  cron
              job).

       dwww-build-menu(8)
              Builds  the Debian Documentation Menu pages.  Needs to be re-run whenever documents
              are  installed  or  removed.   (In  default  configuration   is   called   by   the
              install-docs(8) or by the dwww daily  cron job).

       dwww-index++(8)
              Uses  index++(1)  to build index of the documentation registered with doc-base.  In
              default configuration is called be the dwww weekly cron job.

       For speed reasons, the converted documents are stored in /var/cache/dwww.   The  cache  is
       cleaned by dwww-refresh-cache(8) of old documents to keep it from growing too large.

CONFIGURATION

       dwww  is  configured  via  the  /etc/dwww/dwww.conf  file.   That  file  is a Bourne shell
       (/bin/sh) script that defines some or all the following variables (defaults  are  used  if
       the file doesn't exist, or doesn't define the variable).

   Basic configuration variables
       These  variables  can  be also configured by debconf script. You can change them using the
       following command:
           dpkg-reconfigure dwww

       DWWW_SERVERNAME
              Name of the www server.  Default is localhost.

       DWWW_SERVERPORT
              Port on which the www server listen to.  Default is 80.

       DWWW_USEHTTPS
              If enabled, dwww(1) will connect  to  DWWW_SERVERNAME:DWWW_SERVERPORT  through  the
              HTTPS protocol.  Default is no.

       DWWW_DOCROOTDIR
              The document root for web server.  Default is /var/www.

       DWWW_CGIDIR
              The  directory  which  contains  the  CGI  scripts for your web server.  Default is
              /usr/lib/cgi-bin.

       DWWW_CGIUSER
              Name of the user that the web server uses  to  execute  CGI  scripts.   Default  is
              www-data.

   Browser variables
       DWWW_BROWSER
              Web-browser used by dwww(1) to load dwww main page.

       DWWW_X11_BROWSER
              Web-browser used by dwww(1) to load dwww main page when in X11.

   Path variables
       DWWW_DOCPATH
              Colon-delimited list of directories from which dwww-convert(8) supplies files.  For
              security reasons, it will refuse to convert files outside the directories named  by
              this    variable.     Default   is   /usr/share/doc:/usr/share/info:/usr/share/man:
              /usr/local/share/doc:/usr/local/share/info:/usr/local/share/man:
              /usr/share/common-licenses.

       DWWW_ALLOWEDLINKPATH
              Colon-delimited  list  of  directories  which can be targets of symlinks from files
              from     directories     inside      DWWW_DOCPATH.       Default      value      is
              /usr/share:/usr/lib:/usr/local/share:/var/www.
              For   example,   /usr/share/doc/package/foo.html   may   be  symlinked  to  a  file
              /usr/share/package/foo.html, and this file can be displayed by dwww.

   Cache files locations
       DWWW_QUICKFIND_DB
              Location  of  the  installed  packages  and  programs  cache  file,  generated   by
              dwww-refresh-cache(8)   with   the   help   of   dwww-quickfind(8).    Default   is
              /var/cache/dwww/quickfind.dat.

       DWWW_DOCBASE2PKG_DB
              Location of the cache file, which maps installed doc-base files to packages  names,
              used by the dwww-build-menu(8).  Default is /var/cache/dwww/docbase2pkg.dat.

       DWWW_REGDOCS_DB
              Location of doc-base registered documents contents cache. The cache is generated by
              dwww-build-menu(8) and read by dwww-find(8) Default is /var/cache/dwww/regdocs.dat.

   Documentation indexing variables
       DWWW_INDEX_DOCUMENTATION
              If this variable is set to yes (default), and the  swish++  package  is  installed,
              then dwww-index++(8) will generate index of registered documentation.

       DWWW_INDEX_FULL_TIME_INTERVAL
              Specifies  how  often  (in  days)  dwww-index++(8)  will  generate  full  index  of
              documentation.  The default value is 28.

       DWWW_INDEX_INCREMENTAL_TIME_INTERVAL
              Specifies how often (in days) dwww-index++(8) will run incremental indexing of  new
              documentation files.  The default value is 7.

       DWWW_MERGE_MAN2HTML_INDEX
              If  this  variable  is  set  to  yes,  then  while  generating  index of registered
              documents, dwww-index++(8) will use man pages index generated by man2html  package,
              if it's available.

   Other variables
       DWWW_KEEPDAYS
              How  many  days  should  dwww-refresh-cache(8)  keep  documents  that have not been
              accessed?  Default is 10 days.

       DWWW_TMPDIR
              Directory used by dwww-build(8) and dwww-build-menu(8) to temporally store the  web
              pages  it  generates.   Default  is  /var/lib/dwww.  For security reason any public
              writable directory like /tmp should not be used.

       DWWW_USEFILEURL
              If this variable is set, dwww will use file:/ style URLs to  access  html  files  -
              bypassing  the  CGI  script.  This is faster on slow machines.  Of course, you will
              not be able to read the html documentation on a non-local machine.  Default  is  to
              not enable this feature.

       DWWW_TITLE
              Title to appear on dwww generated files.  Default is dwww: $(hostname)

       DWWW_USE_CACHE
              If  this  variable  is  set to yes (default), dwww will cache accessed documents in
              /var/cache/dwww/db. See dwww-cache(8).

   Deprecated variables
       Since  version  1.10,  dwww  no  longer  uses  the  following   variables:   DWWW_HTMLDIR,
       DWWW_MAN2HTML, DWWW_TEXT2HTML, DWWW_DIR2HTML.

CUSTOMISING DWWW PAGES LAYOUT

       dwww  uses a CSS file for managing the layout of the pages it generates. The file is built
       from two other files, namely /usr/share/dwww/dwww.css, which is a global one, provided  by
       the package, and /etc/dwww/dwww-user.css, a local one, that can be provided by the user to
       override settings from the former file.  The latter file does not exist  by  default,  but
       when  it  exists,  dwww-build(8)  will  append  its contents at the end of generated file.
       Since web browsers tend to use the last one setting defined for a given CSS element,  this
       has the expected effect of customisation.

   Example
       To  use  some  image  as  a  background  for dwww pages, please put something like this in
       /etc/dwww/dwww-user.css:

           body { background: url('http://host/path/to/background.png')
                  repeat; }
           table,pre,code,tt { opacity: 0.7; }

       Please make sure to run dwww-build(8) afterwards.

FILES

       /etc/dwww/dwww.conf
              Configuration file for dwww.  It's not necessary for this file to exist, there  are
              sensible defaults for everything.

       /etc/dwww/apache.conf
              Default  configuration file for various apache-based web servers.  The dwww package
              post-installation script creates symlinks  from  /etc/apache*/conf.d/dwww  to  this
              file.

       /etc/dwww/dwww-user.css
              If  such  a  file exists, its contents will be appended to the dwww.css file.  This
              allows local administrators to customise dwww pages layout.

       /etc/cron.daily/dwww
              Dwww daily cron job, which rebuilds cache directory and dwww HTML pages.

       /etc/cron.weekly/dwww
              Dwww weekly cron job. Uses  dwww-index++(8)  to  rebuild  registered  documentation
              index.

       /var/cache/dwww
              Directory, where are placed various cache files generated and used by dwww.

       /var/cache/dwww/db
              Cache for the converted documents.

       /usr/share/dwww
              Templates for the dwww web pages (used by dwww-build(8) and others).

       /var/lib/dwww
              The  dwww  pages.   The server's document root directory should have a link to this
              directory.
