from jcvi.apps.base import OptionParser # Create an OptionParser object parser = OptionParser() # Set image options for the parser parser.set_image_options() # Add command-line arguments to the parser parser.add_option("-f", "--file", dest="filename", help="input file") # Parse the command-line arguments (options, args) = parser.parse_args() # Use the options in the program print(options.filename)In this example, we create an `OptionParser` object and use the `set_image_options` function to set the image options for the parser. Then, we add a command-line argument to the parser and parse the command-line arguments using `parse_args()`. Finally, we print the value of the `filename` option. Package library: `jcvi.apps.base`
