Epsilon: Both horizontal and vertical screensplitting

Epsilon: Full C-like extensionlanguage. The differences to K&R C are
listed in less then 1 page! Since no key is directly bound to a kernelfunction,
it is easy to configure Epsilon completely to your liking.

>(4) Regular expression search and replace.  [Micro-emacs and tech-edit]

Epsilon: has it!

Epsilon!

Epsilon!

Epsilon can do it!

Again, Epsilon!

Seems to me there is at least one :-) : Epsilon

BTW -- Some other positive facts about Epsilon:
-It's fast enough to be comfortably used on an XT
-It's small enough to be used on a machine without HD
