OK, so unless someone vetoes this the next few hours i will start
shifting files about around 11pm CET today.

It would be great if people could refrain from checking stuff into
trunk/core from then onwards until i've finished. It will take a good
few hours, i'll notify when it is done.


also : should we make some sort of backup first or is everything fully
reversible from the svn command line ? Just to be on the safe side ...

Tag the trunk before you start, and then again afterwards.

But to answer your question, yes everything is reversible from the svn command line.
