I noted this and asked if there is a way to get the revision when the
directory was actually ADDED thus making it possible to extract the
timestamp. I should probably have asked in the subject for the
*revision* it was added and that would have given me the tool to get
the other info...

This is not going to work on the server using svnlook then....

But I am looking for a way to find the revision so this timestamp I am
after can be extracted...

Apart from the timestamp I want for other purposes I am also after the
revision for a changed file when it was last changed (forgot this when
posting).
So I want to create a commit email including info that we are used to
having in the emails we get from our earlier system.
This includes a list with the following for each changed item:

  -Item that was changed (dir or file, available in svnlook changed) 
  -revision it was changed (i.e. the commit revision - simple)
  -revision it was last changed before this commit (how to do this?)
  -a command to diff the new file version with the previous

So my mail will contain this tabular list:
Op  Item    rev  previous_rev  diff_revs

(Op is D U _U or UU from svnlook changed)

All but the two last items are simple....

Not for me because all the hook scripts I have looked at are either
too simplistic (basically pushing svnlook info and svnlook changed
into the mail body) or they are written in a language I do not
master...

I am almost done now, only lacking a way to find the revision of the
last change before the current for all file items in the list of
changes.

I will skip the diff-revs link for now because it relied on the ViewVc
service for the CVS repository where a diff was available and I only
had to calculate the url of the proper diff to put into the email.

Now I first have to install and make working the ViewVc version which
is able to work with svn....
