RE: Problems with hot_backup.py on Windows XP

As I get digest I haven't gotten John Szakmeister's reply yet. However it's
not a problem with the path to svnadmin either. I have modified the entry at
the top of the file and printed it out to screen to be sure [it might be a
windows thing because of the space in the "Program Files" directory but I've
also given the script the short form of the path e.g.
C:\Progra~1\Subver~1\bin\svnadmin with the same results].

As a result I've fallen back on what I know best ... Ant. Here is the script
I've written to backup the repository, keeping seven days worth of backups.
If there have been no change-set commits since the last backup I do nothing
- no backup or clean up. Hope this is of interest to someone. The usual use
at your own risk statements apply. I'm open to questions and suggestions.
