-----------------------------------------------------------------
Here a patch that implements the above. It contains a lot variable renamings
and some backwards-target (deprecated). Maybe we remove them before commit.
To test:
- Apply patch
- remove tags/ folder (unused now). If you have modifications in it, create a
patch
- run "ant test-backwards"
To modify backwards branch:
- run "svn up" in backwards folder
- modify backwards branch
- to now test this modified trunk revision in checkout folder, you can pass
"ant test-backwards -Dbackwards.rev=HEAD", but if you have done "svn up" as
first step this is not needed
- commit changes in backwards branch with "svn commit" (be sure to change to
backwards/$branchname$/src, as src is the root folder of the checkout)
- copy the revision number from commit message and insert into common-build.xml
- (test again and) commit trunk
Please test this and tell me if you like it!

To test:
- Apply patch
- remove tags/ folder (unused now). If you have modifications in it, create a
patch
- run "ant test-backwards"
To modify backwards branch:
- run svn up in backwards folder (recommeneded, but normally not needed)
- modify backwards branch
- to now test this modified trunk revision in checkout folder, you can pass
"ant test-backwards -Dbackwards.rev=HEAD"
- commit changes in backwards branch with "svn commit"
- copy the revision number from commit message and insert into common-build.xml
- (test again and) commit trunk

> Currently we use tags for specifying the revision number in the backwards
> branch that matches the current development branch revision (in
> common-build.xml). The idea is to just specify the corresponding revision no
> of the backwards branch in common-build.xml and the backwards-test target
> automatically handles up/down/co:
> - We just give the rev number in common-build in common-build.xml as a
> property backwards-rev="XXXX". This property is used also in building the
> command line which is also a property backwards-svn-args="-r $backwards-rev".
> By that you can use "ant -Dbackwards-svn-args=''" to force test-backwards to
> checkout/update to head of branch (recommened for developers).
> - we should rename target to "test-backwards" and keep a "test-tag" with
> dependency to that for compatibility
> - The checkout on backwards creates a directory
> "backwards/${backwards-branch}" and uses "svn co ${backwards-svn-args}
> 'http://svn.../${backwards-branch}' 'backwards/${backwards-branch}'". The
> cool thing, the dir is checked out if non existent, but if the checkout
> already exists, svn co implicitely does an svn up to the given revision (it
> will also downgrade and merge if newer). So the test-backwards target always
> updates the checkout to the correct revision. I had not tried with local
> changes, but this should simply merge as an svn up.
> The workflow for committing fixes to bw would be:
> - First use "svn up" to upgrade the backwards working copy to HEAD.
> - Commit the changes
> - Copy and paste the message "Committed revision XXXX" to common-build.xml
> - Commit the changes in trunk
