Martin Smith 17472a2ba3 qdoc: Generate cross-module links-to-links pages
The cross-module link report is modified so that each module
listed in the table is a link to a subpage on which all the
links from the current module to that module are listed. To
check that these links go to the correct place, click on one
to be taken to the actual link. The actual link is marked
with red asterisks. Click on that link to check that the link
goes to the correct page. Repeat this process for all the
links in the table.

Qt 5 Documentation
==================

New in Qt 5.0, each module has its own documentation package. The documentation
resides in the module sources as well as the configuration files needed to build
the module documentation. The main Qt 5.0 Reference Documentation resides in the
qtdoc repository.

There are two ways to build Qt documentation:
* run "make docs" in qt5/ or in the repositories
* run the QDoc tool for each module


Running "make docs"
===================

To build the documentation using Makefiles, qtbase needs to be compiled and
installed.

Running qmake will create make targets to build the documentation:
* html_docs - builds only the HTML documentation
* qch_docs - packages the HTML documentation into QCH files for Qt Creator and
             Qt Assistant.
* docs - runs html_docs and qch_docs

Note: qch_docs needs qhelpgenerator to package the documentation. qhelpgenerator
is in the qttools repository.

These make targets use qmake's QT_INSTALL_DOCS variable as the output directory.
Running "qmake -query" will list the directory set to QT_INSTALL_DOCS.

To create all of the modules' documentation, run "make docs" in the
qt5 directory:
    $> make docs            # builds the bundled modules' documentation

It is also possible to build only a small subset of the documentation by using
make:
    $> cd qtbase
    $> make docs            # builds the documentation for modules in qtbase

    $> cd qtbase/src/sql
    $> make docs            # builds only the Qt SQL documentation


Running QDoc
============

QDoc is the tool for generating Qt documentation and is located in qtbase.
The simplest way to compile QDoc is to compile qtbase or only the tools in
qtbase.

    $> cd qtbase/src
    $> make sub-tools # compiles QDoc

Each module has a QDoc configuration file (.qdocconf). To build a module's
documentation, run the "qdoc" binary and pass the qdocconf file as a parameter.
A mandatory "outputdir" must be specified.

    $> qdoc doc/config/qtdoc.qdocconf -outputdir html

    Note that QDoc will delete the contents of the "html" output directory.

Packaging the Documentation
===========================

To package the documentation, the HTML files must be compiled
into a QCH file (.qch).

Required binaries:
    * assistant - found in qttools
    * qhelpgenerator - found in qttools

To compile the qch file for each module, first enter the output directory that
contains the .qhp file and generate the QCH file.

    $> cd qtbase/doc/qtdoc              #the default path for QT_INSTALL_DOCS for qtdoc
    $> qhelpgenerator qtdoc.qhp         #creates the QCH file called qtdoc.qch

The QCH file can then be loaded in Qt Assistant or Qt Creator. For Qt Assistant,
the QCH file can be registered to automatically load it.

    $> assistant -register qtdoc.qch    #to automatically load the documentation


Global Files
============

The qtbase/doc/global directory contains various files used by the modules to
build the documentation. These include macros, stylesheets, and images for
displaying documentation.

To include these files in a qdocconf, add the following to a qdocconf file:

    include($QT_INSTALL_DOCS/global/qt-module-defaults.qdocconf)


Documentation Structure
=======================
For a typical module, the documentation will reside in the source directory.
The examples and the example documentation are in the "examples" directory.

    qtbase/src/sql/doc/src              #Qt SQL's documentation
    qtbase/examples/sql                 #Qt SQL's examples
