How to remove a revision from the achieve

[Eckard Klotz]

Hello everybody.

Unfortunately I have added something wrong into the my svn archive. I 
know that it is possible how to remove it from the users content. But 
the file is still part of the archive and I want to undo the adding of 
the file.

 * Is it possible to remove it from the whole archive again by deleting
   the last revisions?
 * Or it is possible to copy an archive just until a specific revision
   with a command like hotcopy?

Best regards,

                        Eckard Klotz.
