        Just imagine that your tons of terrabytes of data can be processed  in (parametric) space or
        time (or combination) with only a few (readable!) lines of code waiting only maybe just one
        night.  For this task, we would obviously fall back to tools like cdo or ncl.  However, we
        are stuck to the data analysis options that these provide. That's where pynacolada comes
        into play.  We can now apply any arbitrary pre-defined or user-defined function analysis on a
        huge dataset, and with great performance (from the numpy/matlib library), and very simply.
        
        
        The power of tools lies in their examples. Typical usage of the package, in particular ncmultifunc,
        looks like this::
        
            #!/usr/bin/env python
            # 2013-11-08: Below, you find  just a code snippet from the first tests.. Examples will be added very soon
            # import pynacolada as pcl
            # from Scientific.IO import NetCDF
            # import os
            # import numpy as np
            # import pylab as pl
        
        
            # Example 1: calculate the mean scalar wind speed of the first 10 layers 
        
            fnin = 'laf2009010100.nc'
            #print fnin
            # fobjin = open(fnin,'rb')
            fin = NetCDF.NetCDFFile(fnin,'r')
            fnout = 'laf2009010100_out.nc'
            os.system('rm '+fnout)
            #print fnout
            # fobjout = open(fnout,'wb+''rlat')
            fout = NetCDF.NetCDFFile(fnout,'w')
            # input data definitions
            datin =  [{'file': fin, \
                       'varname': 'U', \
                       'dsel': {'level' : range(30,40,1)}, \
                       'daliases': { 'srlat':'rlat', 'srlon':'rlon' },\
                      },\
                      {'file': fin, \
                       'varname':'V', \
                       'dsel': {'level' : range(30,40,1)},
                       'daliases': { 'srlat':'rlat', 'srlon':'rlon' },\
                       }\
                     ]
            # output data definitions
            datout = [{'file': fout, \
                       'varname': 'u'}]
            # function definition:
            func = lambda U,V: [np.mean(np.sqrt(U**2+V**2) )]
            dnamsel = ['level',]
            pcl.pcl(func,dnamsel,datin,datout,appenddim=True)
            #print fnout
