*** README for KDE's Doxygen tools
***

This directory contains tools and data files for Doxygen
generation. These are the GENERIC files; any module may
override them by putting specific replacements in doc/api/ .
This allows modules to customize their appearance as desired.
The files that may be overridden are:

- doxygen.css      Stylesheet.
- mainheader.html  Header for front page of dox. This should
                   not be terribly different from header.html.
		   It might contain special CSS for the footer.
- mainfooter.html  Footer for front page of dox. This should at
                   least credit Doxygen [1] and point to the dox
		   guidelines [2].
- header.html      Header file for regular pages.
- footer.html      Footer file for regular pages.
- Doxyfile.global  The global (brief) Doxyfile. For a long-style
                   Doxyfile, see KDE PIM's doc/api/Doxyfile.pim.

The tool for generating dox lives in admin/ :

- doxygen.sh       Script that does all the dox generation work.
                   See below for usage information.


In a configured build directory, you can use "make apidox" to
generate the API dox for the module -- assuming it has any, of course.
Writing dox is beyond the scope of this README -- see the notes at
http://techbase.kde.org/Policies/Library_Documentation_Policy .
You can generate dox by hand -- without even having a configured
build directory -- as explained below. There is also documentation
for the special tags you can enter in Makefile.am anywhere
in a module to modify dox generation.

*** Tool usage.
***

Usage:

doxygen.sh [--recurse] [--modulename] [--doxdatadir=<dir>] [--installdir=<dir>]
           <top_srcdir> [<subdir>]

--recurse     Also generate dox in subdirs of the given <subdir>. If no
              <subdir> is given, --recurse is the default and can be
              turned off with --no-recurse.
--modulename  By default, apidox are generated in a subdirectory 
              <modulename>-apidocs/ . You can use --no-modulename to
              suppress the <modulename> and generate the apidox in
              a subdirectory apidocs/ . Modulename is the last part of
              the <top_srcdir> (usually a KDE SVN module name).
--doxdatadir=<dir> Locate the HTML header files and support graphics.
              In tdelibs, the subdirectory doc/common/ contains these
              files (and this README). In an installed KDE system, 
              $TDEDIR/share/doc/tde/HTML/en/common/ contains a copy.
              This argument is mandatory if doxygen.sh can't guess where
              the doxdata lives.
--installdir=<dir> Locate the directory where apidox from other modules
              is installed. Subdirectories named *-apidocs/ under the
              named <dir> are searched for tag files, for cross-module
              cross-referencing.



How to generate dox manually: <TODO>
Plan to fit these tools into ../Doxyfile.am: <TODO>
Differences with current dox: <TODO>

# A shell script that builds dox without all the tedious mucking about with
# autoconf and configure. Run it in the "top builddir" with one argument,
# the "top srcdir". Something like this:
#
# cd /mnt/build/tdepim
# sh /mnt/src/tdepim/doc/api/doxygen.sh /mnt/src/tdepim
#
# You can also build single subdirs (for instance, after updating some
# dox and you don't want to rebuild for the enitre module) by giving the
# subdirectory _relative to the top srcdir_ as a second argument:
#
# sh /mnt/src/tdepim/doc/api/doxygen.sh /mnt/src/tdepim kpilot/lib
# 
# When generating dox for tdelibs, a tag file for Qt is also created.
# The location of Qt is specified indirectly through $TQTDOCDIR or,
# if that is not set, $TQTDIR, or otherwise guessed. You may explicitly
# set the location of a pre-generated tag file with $TQTDOCTAG. One
# typical approach might be:
#
# TQTDOCTAG=$TQTDIR/doc/qt.tag TQTDOCDIR=http://doc.trolltech.com/3.3/
#
# Finally, there is a --no-recurse option for top-level generation
# that avoids generating all the subdirectories as well. It also
# suppresses cleaning up (rm -rf) of the dox direction beforehand.
#
# Post-finally, there is a --no-modulename option that builds the
# dox in "apidocs/" instead of "modulename-apidocs". The former is
# compatible with the KDE 3.4 build system, the latter is more convenient
# for the installed dox.

#
# A shell script to post-process doxy-generated files; the purpose
# is to make the menu on the left in the file match the actually
# generated files (ie. leave out namespaces if there are none).
#
# Usage: doxyndex.sh <toplevel-apidocs-dir> <relative-html-output-directory>
#
# Typically, this means $(top_builddir)/apidocs and something like
# libfoo/html for the output. For the top-level dig, set relative-html
# to "." . In non-top directories, both <!-- menu --> and <!-- gmenu -->
# are calculated and replaced. Top directories get an empty <!-- menu -->
# if any.
