Updated version, thanks to cjs on irc:


# Examines a subversion directory.
# If a file has been added, add the file to the repository.
# If a file has been deleted, delete the file from the repository.
# And save all modified files.
# And then do a 'svn up'.

# Meant to do automated versioned backups of a directory for
# non-technically inclined users.
