Thanks for this, it's very helpful. I've printed the first two chapters of the book and am RTFMing :) The initial quality of the manual is quite impressive!
One statement I can make that might clear up some confusion is that I don't care if the names "trunk", "branches" and "tags" are used in the repository's internals and theory. I was just hoping to ensure the trunk always related to code in the /home/username/ folder.
However, if my thinking is now correct, code doesn't 'live' in a normal file system folder *until* a version is extracted from the SVN internals to a folder. Is that correct? If this is the case, my scenario would need a situation where any code checked in to the trunk would automatically be outputted to a real folder. If I was to draw up a basic work flow diagram of what I am trying to achieve, would you be able to take a look?
