+  V2.2.7: Hans.Vahlenkamp@noaa.gov
+          Synchronize output file before closing and check for errors.
   V2.2.6: Seth Underwood <Seth.Underwood@noaa.gov>
           Updates for C99 standards.
   V2.2.5: Seth Underwood <Seth.Underwood@noaa.gov>
           Fix for NetCDF files that do not have a time dimension.
   V2.2.4:  Tushar.Mohan@noaa.gov
            Round memory footprint to ceiling integral value.
-
   V2.2.3:  Tushar.Mohan@noaa.gov
            Fixed handling of -k when -x is set.
            Print memory estimate in MB when -x is used without -v.
            Fixed help message for -k and -x.
            If user sets blocking factor > # records (nrecs), set bf to nrecs
-
   V2.2.2:  Tushar.Mohan@noaa.gov
            Added a -x option to print estimate resident memory footprint and exit
            Changed default blocking factor 1, so the combine behaves as the
            combine of the past if no "-k" option is set. This is useful
            for low-memory nodes.
-
   V2.2.1:  Do not bail out when we cannot write variables to output file.
            Instead, issue a warning and set an error condition. Continue
            processing.

            only showed up in certain rare input conditions.
            Added -M to show memory usage statistics.
            Added -V to print version information.

   V2.2:    Added record blocking (see, the -k option) to the memory buffering
            code. This significantly improves performance, by buffering multiple
            records of decomposed variables in memory. Output I/O performance
