The man page says "Portions of this code used for Lempel-Ziv-Huffman encoding were based on Rahul Dhesi's Zoo archiver which was adapted from Haruhiko Okumura's ar archiver".

Gzip says "The code in this file is directly derived from the public domain 'ar002' written by Haruhiko Okumura."

Note that Haruhiko Okumura was also involved in the development of LHArc.
