+This is a patched version of Qt.  It may include changes made by KDE
+and Qt developers that have either not been accepted for inclusion
+into Qt, or have been accepted for a later version of Qt than this
+one.
+
+1. Configuring Qt
+=================
+
+The recommended compile line is:
+
+--default-config-begin--
+
+  ./configure -qt-gif -debug -fast -no-separate-debug-info \
+     -system-libpng -system-libjpeg -system-zlib \
+     -dbus -webkit -plugin-sql-mysql \
+     -nomake examples -nomake demos -prefix <installdir>
+
+--default-config-end--
+
+It contains "-debug", which greatly improves the use for backtraces (but
+also needs a lot more disk space and makes things slower). To build in
+release mode, replace it with "-release".
+
+It also contains "-no-separate-debug-info", which disables separate .debug
+files. Instead, the debug information will be built into the libraries.
+This option is needed when you install Qt.
+
+If you don't install Qt, it can be useful to disable this option,
+thus having separate debug symbol files. With separate debug files, you can
+just move those debug files to another directory to remove Qt debug symbols.
+Moving the files back will enable Qt debug symbols again.
+This is useful if you rarely need to step into Qt functions during debugging,
+because GDB loads much faster and uses less memory without Qt debug symbols.
+In the rare case you need to step into Qt code, you can temporarily enable
+debug symbols again by moving the debug files back. You can even load the Qt
+debug symbols from within GDB on demand, using the "symbol-file" command.
+
+If you are planning to compile Qt using an Icecream cluster you have to
+pass the option -no-pch (no precompiled headers) to configure to make
+distributed compilation work.
+
+2. Compiling Qt
+===============
+
+To compile Qt on a Unix platform, run:
+
+   export MAKEFLAGS=-j2
+   make
+   make install
+
+If your computer has more than one core or processor, you may consider
+increasing the "2" above. If you've got a compile farm available, you
+should adjust the -j argument to match the number of slots in that
+farm.
+
+3. Modifying & rebuilding Qt
+============================
+
+If you make modifications to the Qt source code, you don't need to
+build everything again. Simply go to the directory containing the
+Makefile closest to the files you changed and run "make" again.
+
+For example, if you've modified src/corelib/io/qiodevice.cpp, do:
+
+   cd src/corelib
+   make
+
+If you make a change that is not temporary, you should create a Git
+commit out of it. However, you shouldn't push those changes to
+kde-qt.git. If you have a fix that benefit others, see the "Creating
+kde-qt.git modifications" section below.
+
+4. Building Qt examples and demos
+=================================
+
+The "-nomake examples -nomake demos" arguments to the configure script
+mean that those two sections will not be configured for building,
+which is unneeded for usage of the library.  If you want to compile
+the examples or demos later, just enter either directory and type:
+
+   qmake
+   make
+
+5. Build Qt tests
+=================
+
+(Official information: http://qt.gitorious.org/qt/pages/QtAutotestsEnvironment)
+
+In order to run Qt tests, you must have a "developer build" of Qt. For
+that, you need to reconfigure Qt and add the "-developer-build"
+option. That option is technically equivalent to the options:
+
+   -debug -prefix $PWD -DQT_BUILD_INTERNAL
+
+To run a test, go to its source dir in tests/auto/testname. Type
+"make" to build it, then run it (either ./tst_testname, or "make install").
+
+6. Building Qt documentation
+============================
+
+To build and install the documentation, run:
+
+   make docs
+   ./config.status
+   make install
+
+It is necessary to do this once only, even if you rebuild Qt later.
+
+7. Using Qt uninstalled
+=======================
+
+To use without having to install it, configure it as follows:
+
+   ./configure <other configure options>  -prefix $PWD
+   make sub-src
+   make sub-tools
+
+Attention: DO NOT run
+
+   make install
+
+If you do, Qt will overwrite your include/ directory with its
+installation.
+
+8. Creating kde-qt.git modifications
+====================================
+
+If you have fixed a bug in Qt or modified it in any way that may
+benefit others, please share your change in the form of a patch. Do
+not commit your changes directly to the main branch because they
+may be lost in a future update if they have not been added to the
+official Qt release.
+
+The exception to the above rule is that if the fix has been accepted
+by the Qt developers (and so will appear in the very next release of
+Qt), then it should be simply cherry-picked from the Qt development
+branch. Note that you shouldn't do this for changes that have been
+accepted into a release which is not the very next.  In this case, you
+should use the following command:
+
+   git cherry-pick -x SHA1_OF_THE_FIX
+where SHA1_OF_THE_FIX is the SHA-1 of the commit that you want to
+introduce. Then push the change to the server.
+
+In all other cases, before creating a patch, it is recommended to
+contact the Qt developers via a new task in
+http://bugreports.qt.nokia.com and explain the situation. There may be
+a solution for the problem already or a new direction that should be
+accounted for.
+
+To create a patch, do the following:
+  a) look at the listing of branches in
+  http://qt.gitorious.org/+kde-developers/qt/kde-qt/commits/HEAD and
+  select the next number.
+
+  b) create a new branch out of a clean, released version of Qt, (for
+  example, 4.5.1), using the number above and a brief description of
+  your fix. For example:
+      git checkout -b patches/0180-window-role v4.5.1
+  You can see the available released versions of Qt with:
+      git tag
+
+  c) make your changes to the Qt source code and verify that it
+  compiles, links and works (please run the respective unit tests from
+  tests/auto in the source tree).
+
+  c) commit your changes to Git, using the "git commit" command. Please
+  see http://qt.gitorious.org/qt/pages/GitIntroductionWithQt and
+  http://qt.gitorious.org/qt/pages/QtCodingStyle for information on
+  how to create commits
+
+  Note that you are allowed to create as many commits as necessary to
+  accomplish a working change that can be easily reviewed.
+
+  e) merge the change to the patch branch, for example, 4.5.1-patched:
+      git checkout 4.5.1-patched
+      git merge patches/0180-window-role
+
+  f) merge the patch branch to master:
+      git checkout master
+      git merge 4.5.1-patched
+
+  g) push the changes you made to your branch and to the main server:
+      git push git@gitorious.org:qt/kde-qt.git master 4.5.1-patched patches/0180-window-role
+  (Don't forget to list all 3 branch names)
+
+Don't forget to submit your patch to using the Qt Contribution Model,
+along with the long description of the issue found. See
+http://qt.gitorious.org/qt/pages/QtContributionGuidelines for
+information how. You can submit the branch you've just sent to the
+server.
+
+9. Troubleshooting: Re-configuring and re-compiling
+===================================================
+
+For those updating the source in a directory where Qt has already
+been compiled, you may need to run the following commands from the
+top directory of your Qt sources:
+
+	find . -name '*.moc' | xargs rm
+
+Sometimes ./configure will refuse to run.  You may need to:
+	rm .qmake.cache
+
+If you think you may have run "make install" on an install-less Qt
+(srcdir == $QTDIR), run:
+
+	rm -rf include
+	bin/syncqt
+
+10. Maintenance: updating kde-qt to a newer Qt version
+======================================================
+
+When a new version of Qt is released, do the following to update the
+repository (assuming Qt 4.6.1 is the release you're updating to):
+
+ a) rebase each of the individual patches against this new version.
+      for branch in patches/*; do
+        git checkout -b $branch origin/$branch
+        git rebase v4.6.1
+        resolve conflicts
+      done   # Note: pseudo-shell, don't try to run this
+
+    If a given branch is no longer valid (it's been applied to this Qt
+    version), then delete it on the server:
+      git push origin :$branch
+
+ b) create a new "patched" branch locally, starting on the release tag:
+      git checkout -b 4.6.1-patched v4.6.1
+
+ c) merge the patch branches and the README branch, one by one. There
+    should be no conflicts at this stage; if there are, it indicates
+    one patch conflicts with another.
+      git merge patches/0997-patch1
+      git merge patches/0998-patch2
+      git merge patches/0999-patch3
+      # etc.
+      git merge README
+
+ d) overwrite the master branch's contents with the new branch. If the
+    Git merge strategy "theirs" exist (it doesn't as of Git 1.6), use
+    it:
+      git checkout master
+      git merge -s theirs 4.6.1-patched
+
+    If it doesn't exist, do the equivalent by inverting the point of
+    view:
+      git checkout -b tmp 4.6.1-patched
+      git merge -s ours master
+      git checkout master
+      git merge tmp
+      git branch -d tmp
+
+    Also possible using Git plumbing:
+      git checkout master
+      git merge -s ours --no-commit 4.6.1-patched
+      rm .git/index
+      git read-tree 4.6.1-patched
+      git commit
+
+  e) push everything to kde-qt.git, including the new Qt. Note that
+     the individiual patch branches will require force, because they
+     have been rebased (that is, the new branch tip is no longer a
+     direct descendant of the previous tip).
+
+      # Push the individual patch branches with force
+      git push -f origin patches/0997-patch1 patches/0998-patch2 patches/0999-patch3 etc
+      # Push the tag, the new patched branch and master
+      git push v4.6.1 4.6.1-patched master
