The racket --lib ${module_name} --main ${arguments} command is used to run a Racket program with specified module name and command line arguments.

Here is a breakdown of the command:

• racket: This is the command to execute the Racket interpreter or runtime system.
• --lib ${module_name}: This option is used to load a specific module in the program. ${module_name} should be replaced with the actual name of the module you want to load.
• --main ${arguments}: This option is used to specify the main function or entry point of the program and provide command line arguments to it. ${arguments} should be replaced with any command line arguments you want to pass to the main function.

By using this command, the Racket interpreter will load the specified module (specified by ${module_name}) and execute the main function with the provided command line arguments (specified by ${arguments}). This allows you to run and test specific parts of your Racket program from the command line.
