# command line
# alright so basically
# py -m beatman -i "path/to/input" -o "path to output" -p "pattern"
# takes song from input path, beatswaps with the pattern, and writes to output
# if output not specified, it just goes to output folder
# if input is not specified it opens a file selector
# just "py -m beatman" will bring up a file selector and ask for pattern
