I think it can be replacable with below Tsugio's source.

Debian package uses his (Tsugio's) source. It also can handle -lh7-
format.  I already contacted with him, but his responce were too slow
(waited over 4 months, or more!), and he thought changing license was
very difficult. LHa for unix was hacked by many people at least over
13 years, they have treated thier license as "vague". Historical
reason makes diffcult to change their license.

It seems good idea, but we have to make them push thier source as
public, and then port into unix... I don't know porting from amiga
into unix is easy issue or not.

We can get lha archive format information easily.

I don't know there was DFSG-Free version in past.
Does anyone try to make free lha archiver?
