dired cmd to split frame into n equal-sized windows

[David Combs]

I saw this command (in dired?), tried it, LIKED IT!, and
forgot to write it down.  (Maybe it was all a dream?)

The way it worked, as I remember (or dreamed), was
that you marked some files, say n of them, in a dired-buffer.

Thin, you executed this command, and presto!, those n
files instantly appeared in front of you, each with
roughly the same number of lines.

Neat command!

Please, WHAT IS ITS NAME?


THANKS!


David
