Requirements/Dependencies
-------------------------

DocBookWiki is built using the phpWebApp framework
(htpp://phpwebapp.sourceforge.net) . It runs with apache and php > 4.3
. For keeping the history of the modifications of the documents it
uses subversion (which can also be used to update the application to
the latest version). Some other tools/programs/packages that are
required or needed are listed below.

* It requires the php command line interface (debian package php4-cli
  or php5-cli ) for running some shell scripts written in php
  (pre-processing, post-processing, etc.)

* It requires xsltproc for explode/implode and other processing and
  transformations of XML content.

* Requires xmllint (debian package libxml2-utils ) for XML checking
  and DocBook validation.

* Requires mailx or any other program that can send emails (called by
  the php function mail() ).

  Tip: If the box of docbookwiki has no connection to internet and the
       mails are send to the local users, then I use dnsmasq as well,
       so that MX queries to the local domain are resolved quickly.
       Otherwise there are delays while sending emails, which slow down
       the work of the application.

* Requires sed and gawk , which are used in some shell scripts.

* Requires openssl for encrypting passwords (the command openssl
  passwd ).

* Needs sudo so that apache can run commands with the permissions of
  the DATA_OWNER.

* Needs swish-e for indexing the content and for searching.

* Needs xmlto , docbook-utils , and dblatex for converting DocBook to
  other formats: HTML, LaTeX, PDF, TXT, etc. ( dblatex requires python
  etc.)

* Needs mysql for installing and using webnotes.

* Needs msgfmt (package gettext ) to convert l10n files from *.po to
  *.mo . However this can be done in another system as well and the
  files can be transfered to the docbookwiki system.

* Needs doxygen and phpDocumentor for generating codedocs; doxygen
  needs graphviz for generating UML diagrams. phpDocumentor can be
  downloaded from:
  https://sourceforge.net/project/showfiles.php?group_id=11194&release_id=500918

If you compile SWISH-E (http://swish-e.org) form the source, then keep
in mind that DocBookWiki requires the XML2 parser of swish-e (in order
to index the XML content). For this reason, the libraries libxml2 and
libxml2-devel must be installed in the system before compiling
swish-e.

In RedHat/Fedora xsltproc is in the package libxslt . Also these RPM
packages are required, in order to make the content: docbook-dtds ,
xml-common , sgml-common . In order to generate the formats, these
packages are needed as well: xmlto , xmltex , docbook-style-xsl ,
docbook-utils , docbook-utils-pdf , docbook-style-dsssl (and their
dependencies as well: openjade , perl-SGMLSpm , passivetex , jadetex ,
tetex , tetex-fonts , tetex-latex , tetex-dvips , psutils , netpbm ,
netpbm-progs , libtiff , etc.).

In general, 'Applications/Authoring and Publishing' group of packages
should be installed in order to include the neccessary tools about
SGML, XML, XSL, DocBook, etc. in RedHat/Fedora.
