unp does not have a website.
atool is written in perl.
dtrx is written in python.
e is written in ruby.

So I don’t like unp and atool.
dtrx has more features I need then e. (like “make sure everything is in 1 subdirectory”), and -t (list) support. So that’s my pick.

@gogi-goji beautiful, tnx 4 sharing!

But, i must agree these things are convenient, and if someone cares to add a gui to it, then they would be noob friendly too
