Usage: micro-syntax FLAGS* FILE*

Recognizes the syntax of each file,, and prints it to stdout.

If there are no files, reads stdin.

Flags:
  -h --help   This help

  -l --lang   Language: py|cpp|shell|...
  -t          Print tokens as TSV, instead of ANSI color
  -w          Print HTML for the web

  -m          More color, useful for debugging tokens

  -n --no-comments    Omit comments
  -o --comments-only  Only print comments
  -e --empty-strs     Substitute string literals for empty strings
     --color          on off always more
