#!/usr/bin/env nomsu -V6.15.13.8
#
Auto-format Nomsu code. Usage:
nomsu -t format [-i] file1 file2...
If the "-i" flag is used, the file will be edited in-place.
If the "-q" flag is used and an error occurs, the original file will be printed.
If no files are passed in, this will read from stdin.
use "filesystem"
use "commandline"
