+Calls nextcloudcmd to sync a source directory and server url. The script
+triggers a synchronization when (i) the source directory was changed or (ii)
+after some period, whatever happens first. The nextcloudcmd is called with
+netrc for login.
+
+Usage:
+ $0 [OPTIONS] source_dir server_url
+ $0 -h
+
+OPTIONS:
+  -h        Show this text
+  -o        One-shot instead of looping
+  -s        Silent, be less verbose
+  -t SECS   Sync period if nothing changed locally.
+            Default: 180
+
+EXAMPLE
+    $0 ~/.vimwiki https://cloud.example.com/remote.php/webdav/vimwiki
