The original Liero data and binary files are copyright 1998 Joosa Riekkinen They are, unless otherwise stated, available under the WTFPL license: The LIERO.EXE binary contains the SMIX sound library: The author of SMIX has stated that it is available under a BSD-3-Clause license, with a request for donations for use in commercial products. LIERO.SND contains sounds from Molez: Molez is freeware and freely distributable. The license in LIEROENG.TXT is no longer valid but the file is kept for nostalgic purposes ;)
