+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
