The command "swc" is using a program or script named "swc" to execute some actions.
"${path-to-input_directory}" and "${path-to-output_directory}" are placeholder variables indicating the paths to an input directory and output directory, respectively.
So in order to understand the command fully, you need to replace "${path-to-input_directory}" with the actual path to the directory you want to use as input. Similarly, replace "${path-to-output_directory}" with the actual path to the directory where you want the output to be saved.
Once you replace the placeholder variables with actual paths, the command will run the "swc" program or script with the provided input directory and output directory as arguments ("--out-dir" is specifying the output directory). The specific actions performed by the "swc" program or script will depend on its functionality or purpose, which is not provided here.
