No !
But remember, all the Unix/Linux clones, for example, are distributed
on a non-commercial basis (Freeware, respectively GPL Open Source),
so the situation there maybe slightely different !

Oh, don't underestimate this issue !
In fact, there are lots of nasty lawsuits regarding names, links, looks & feels, etc... :-(

Well, these are my words, so I can't really argue against them ... ;-)

Even further, it's now only "part of UnixTree", UnixTree is "just" an updated
version of the original "xtree for UNIX" code !!

Well, in fact, he has not "regained" the code's legal rights, but indeed
"retained" it, for he has "licensed [it] to XTree company on royalties basis"
(quoted from the XTFP stories section), the xtree for UNIX code *never* has been
"owned" neither by XTree Company nor by Central Point or Symantec !!

> this too is another form of "legal heritage" from XTree.

Maybe legal, yes, however, but definitely not a "code heritage", or so, cause
Rob Juergens once wrote "xtree for UNIX" completely on his own (like Kim Henkel
did with ZTree), without ever having seen the code from the original XTree for
DOS versions !

Apart from that, it would have been no great use anyway, to try to "port" the
code of a DOS Assembler program to a "C" Unix language one !

Hm, a really cute metaphor ... ;-)

I see !
