% nccat -- Concatenate two netCDF files.
%  nccat(theDestinationFile, theSourceFile1, theSourceFile2, ...)
%   concatenates theSourceFile1, ... onto theDestinationFile.  This
%   routine behaves like the "nccat" C-language program, which
%   concatenates record-variables, but no other entities.  The files
%   must have the same record structure.
