- * dos2unix for BusyBox

- * dos2unix '\n' convertor 0.5.0
- * based on Unix2Dos 0.9.0 by Peter Hanecak (made 19.2.1997)
- * Copyright 1997,.. by Peter Hanecak <hanecak@megaloman.sk>.

- * dos2unix filters reading input from stdin and writing output to stdout.
- * Without arguments it reverts the format (e.i. if source is in UNIX format,
- * output is in DOS format and vice versa).
