This is already an issue; there is a ".config" directory that stores the
client's config data. Probably the best solution is to push the
client's data into a further subdirectory. You would then have a
structure like this:

  $client_dir/
  $client_dir/client-files/saved-file.xml
  $client_dir/client-files/saved-file-2.xml
  $client_dir/config-data/foo
  $client_dir/config-data/bar
  $client_dir/log.txt

rather than

  $client_dir/
  $client_dir/saved-file.xml
  $client_dir/saved-file-2.xml
  $client_dir/.config/foo
  $client_dir/.config/bar
  $client_dir/.log.txt
