I have a hard time getting to understand this...
Do you mean that using "trunk", "branches" and "tags" as directories
is entirely voluntary? Does this also mean that files inside a
tags/something directory can be modified and committed, thus changing
the content of the tag?
In my CVS life there is a clear distinction between a tag and a branch
in that it is not possible to commit changes into a tag but it *is*
into a branch. So tags are immutable snapshots of the situaton at a
specific moment in time. Is this not the case in svn?

I looked at it but could not make much of it since it is in Python, a
language I am very much not familiar with. I am doing ObjectPascal
(Delphi and FreePascal) for windows and linux platforms and also C
(not C++ though) for embedded controllers...
The Python code was very hard reading for me so I will try my way
along the Pascal rouad to get a commithook mailer that replicates the
emails we got out of CVS.
More experientation has shown up how I can use "svnlook tree" properly
to extract the files in a new tag, so that part is at least covered
now.
