Edition_01 is a directory, where is older major version of this
software. The most important difference to current version is this:

Shell switching to best possible shell is no more done during login.
Hence, you must change your default shell to zsh (or ask your sys
admin to do it).

I decided to stop using those shell switching systems, when I got some
problems during login. And Unix systems I use have zsh, anyway.

I also disabled linux_logo in some machines, because I had non-working
self-compiled binary of it.
