[4106]	65	!> NetCDF output module to write data to NetCDF files.
	66	!> This is either done in parallel mode via parallel NetCDF4 I/O or in serial mode only by PE0.
[4597]	67	!>
	68	!> @bug 'mode' is not always checked. If a routine is called with an unknown mode (e.g. a typo),
	69	!> this does not throw any error.
