DESCRIPTION

       ncpdq  packs  or  re-shapes  variables  in input-file and stores them in output-file.  Which variables to
       pack/unpack are determined by the packing policy encoded in the pck_plc argument to the -P switch.  Valid
       pck_plc  options are all_new, all_xst, xst_new, and upk.  The numeric type of variable to pack or re-pack
       a variable to is determined by the packing map encoded in the pck_map argument to the -M  switch.   Valid
       pck_map options are flt_byt, flt_sht, hgh_byt, hgh_sht, and nxt_lsr.

       ncpdq  re-shapes  variables  in  input-file  by  re-ordering and/or reversing dimensions specified in the
       dimension list.  The dimension list is a comma separated list of dimension names, optionally prefixed  by
       negative  signs,  that  follow  the  -a  switch.   To re-order variables by a subset of their dimensions,
       specify these dimensions in a comma-separated  list  following  -a,  e.g.,  -a  lon,lat.   To  reverse  a
       dimension,  prefix  its  name with a negative sign in the dimension list, e.g., -a -lat.  Re-ordering and
       reversal may be performed simultaneously, e.g., -a lon,-lat,time,-lev.

       Users may specify any permutation of dimensions, including permutations which change the record dimension
       identity.   The  record dimension is re-ordered like any other dimension.  The record dimension is always
       the most slowly varying dimension in a record variable.   The  specified  re-ordering  will  fail  if  it
       requires creating more than one record dimension amongst all the output variables.
