  18 Calls nextcloudcmd to sync a source directory and server url. The script
  19 triggers a synchronization when (i) the source directory was changed or (ii)
  20 after some period, whatever happens first. The nextcloudcmd is called with
  21 netrc for login.

  23 Usage:
  24  $0 [OPTIONS] source_dir server_url [ARGS...]
  25  $0 -h

  27 OPTIONS:
  28   -h        Show this text
  29   -o        One-shot instead of looping
