I can't do that. I'd be happy to, but my company refuses to sign the copyright disclaimer. :(

I'll try to find out someone who might be willing to write some lisp.

Yours sincerely, Vladimir Nikishkin

We need first to add a capability to extract archive members to files.
This is currently not part of arc-mode.el: it can only "extract" a
member to a buffer, let you edit it, and then put the edited copy back
into the buffer.  Extraction to files (a.k.a. "unarchiving") is not
yet supported.

Would you like to work on adding this to arc-mode.el?
