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.
