# Explanation:
# The script starts by importing the necessary modules, argparse and GetoptError from getopt.
# Then, a main function is defined to execute the script.
# Inside the main function, a parser object is created using the argparse module and a description is added to it.
# Two arguments are added to the parser object, one for the input file and one for the output directory.
# The arguments are then parsed and stored in the args variable.
# Finally, the main function is called if the script is being executed directly.

# Import the necessary modules
import getopt # Import the getopt module for parsing command line arguments
import sys # Import the sys module for accessing command line arguments
from os import path # Import the path module from the os library for working with file paths
