# files: 
# combine-ncc -- combines lm3 netcdf restart files (in general, any compressed-
#    by-gathering set of files) into one.
#    v 2.0.1 -- a minor bug fix: number of input files was used incorrectly in
#       argument sanity check at the beginninhg of the program
#    v 2.0.2 -- fixed an error in inq_compressed_dim (nfu_compress.F90), where 
#       value of 'compress' attribute was not initialized to empty string every 
#       time before reading, resulting in possible confusion when there is more
#       than one compressed dimension per file
#    v.2.0.3 -- fixed an error where an unlimited dimension in input file was
#       converted to regular dimension of corresponding size in the output
#    v.2.0.4 -- introduced an ability to skip negative indices in compressed
#       dimension -- important for the cases when compressed index is zero
#       length (e.g., no cohorts in compute domain), but the file structure
#       must be preserved
#    v.2.0.5 -- limited minimum size of the compressed dimension to 1 -- important
#       in cases when the files don't have any valid compressed points in them, 
#       for example lake model restarts if there is no lakes at all. 
# decompress-ncc -- decompresses a compressed-by-gathering netcdf file into
#    a regular netcdf file
# gentest -- generates test data for restart combination utility
# nfu_c_test -- test of nfu compressed utilities
