 This module implements the Scientific.IO.NetCDF API to read and create
 NetCDF files. The same API is also used in the PyNIO and pynetcdf
 modules, allowing these modules to be used interchangebly when working
-with NetCDF files. The major advantage of ``scipy.io.netcdf`` over other 
+with NetCDF files. The major advantage of ``scipy.io.netcdf`` over other
 modules is that it doesn't require the code to be linked to the NetCDF
 libraries as the other modules do.
