The purpose would be to access repository at:
but the server is a self-signed SSL certificate, hence the prompt.
No, I would not recommend automatic for remote repository either.

And what about cron job that runs as an unprivilaged user without any
$HOME or shell? Also, even if the user does have a valid $HOME, I find
that `svn' does occasionally forget it's cache for these cron job
unprivilaged users with valid HOME...
