-# Script for updating/adding specified netCDF variable metadata
-#   attribute values.
-#
-# Syntax:
-#   cdo_post_prep.sh variable_file input_netcdf output_netcdf
-#
-#   Arguments:
-#
-#     variable_file: ASCII formatted file containing netCDF variables
-#                      and the respective metadata attributes to be
-#                      updated/added; the supported format is as
-#                      follows.
-#
-#     <netCDF variable name> <netCDF metadata attribute name>
-#       <netCDF metadata values>
-#
-#       An example using the format described above is as follows.
-#
-#     SST coordinates geolon,geolat,time
-#     uo coordinates geolon_u,geolon_u,time
-#     vo coordinates geolon_v,geolon_v,time
-#
-#       The example above will perform the following task using this
-#       script.
-#
-#       * Assign the netCDF metadata attribute `coordinates` for
-#         variable `SST` the values `geolon,geolat,time` and update
-#         the `output_netcdf` file path.
-#
-#       * Assign the netCDF metadata attribute `coordinates` for
-#         variable `uo` the values `geolon_u,geolat_u,time` and update
-#         the `output_netcdf` file path.
-#
-#       * Assign the netCDF metadata attribute `coordinates` for
-#         variable `vo` the values `geolon_v,geolat_v,time` and update
-#         the `output_netcdf` file path.
-#
-#     input_netcdf: The netCDF-formatted file path containing the
-#                     variables defined in `variable_file`.
-#
-#     output_netcdf: A netCDF-formatted file path to contain the
-#                      specified variables remapped to the destination
-#                      grid projection.

-# _comma_split_string - Split a comma-delimited string into an array.
-#
-# Description:
-#   This function takes a comma-delimited string as input and splits
-#     it into an array. Each element in the resulting array is
-#     obtained by splitting the input string at commas and then
-#     removing leading and trailing spaces.
-#
-# Parameters:
-#   $1 - The comma-delimited string to split.
-#
-# Global Variables:
-#   global_array - An array containing the split elements.
-#
-# Example usage:
-#   _comma_split_string "item1,item2 item3,item4"
-#   for element in "${global_array[@]}"; do
-#       echo "$element"
-#   done
-#
-# This example will split the input string into individual elements
-#   and print each element on a separate line.

-# _strip_whitespace - Remove whitespace from a string.

-# Description:
-#   This function takes an input string and removes all whitespace
-#   characters (spaces, tabs, and newline characters) to produce a
-#   cleaned output string.
-#
-# Parameters:
-#   $1 - The input string from which whitespace will be removed.
-#
-# Return:
-#   The cleaned string with no whitespace.
-#
-# Example usage:
-#   cleaned_string=$(_strip_whitespace "   This is a string   with spaces  ")
-#   echo "Cleaned string: \"$cleaned_string\""
-#
-# This example will remove all leading, trailing, and internal
-# whitespace from the input string and display the cleaned result.
