## LANGUAGE

- trainfuck is not case-sensitive
- except for ALL ABOARD and END OF THE LINE

## USAGE

`trainfuck -h`:

```
TRAINFUCK: CHOO CHOO

Usage:
 trainfuck -h|--help
 trainfuck [-w WIDTH] [FLAGS...] INPUTFILE [-o OUTPUTFILE]

Parameters:
 INPUTFILE       The trainfuck file to process.
                 If INPUTFILE ends in .tf or .trainfuck, it will be interpreted
                 as a TRAINFUCK file; if it ends in .bf or .brainfuck, it will
                 be interpreted as a BRAINFUCK file.  Otherwise, the file will
                 be assumed to be the default filetype (trainfuck).

 -w WIDTH        Set the brainfuck output width (default: 42).
 -o OUTPUTFILE   Where to send transpiled brainfuck (default: /dev/stderr).
 --              Stop processing arguments; interpret the rest as filenames

FLAGS:
 -h, --help          Show this help
 -c, --comments      Show comments (default)
 -C, --no-comments   Hide comments
 -z, --compact       Show "compact" comments (default)
 -Z, --no-compact    Show "wide" comments
 -x, --execute       Execute trainspiled brainfuck
 -X, --no-execute    Only trainspile, do not execute (default)
 -t, --trainfuck     Force TRAINFUCK mode: interpret files as trainfuck
 -b, --brainfuck     Force BRAINFUCK mode: interpret files as brainfuck
 -q, --quiet         Don't print any more than is necessary
