Kurz:         Auf ENV-Variablen optimierte Ram-Disk, V1.0

This is a kind of RAM disk handler specialized for environment variables
that are usually found in RAM:ENV. Because environment variables
(short: ENV vars) are usually quite small and there are lots of them,
HappyENV is optimized for lots of small files. This brings you the
following advantages:

* Smaller memory usage
* Faster accessing of ENV vars
* You can do "delete RAM:#? all" without hurting ENV vars
* Conceptionally much cleaner than the RAM: concept

This works by providing you an AmigaDOS(TM) handler for a ENV: device.

And there is an additional feature:
Every time a ENV var is accessed and cannot be found in ENV:, HappyENV
tries to copy it automatically from ENVARC:. This makes it possible to
leave out copying the whole ENVARC: directory to ENV: during boottime.
To avoid many disk accesses HappyENV remembers files that are not in
ENVARC:. So the additional advantages are:

* Faster booting
* Even smaller memory usage
* You do not have to clean up ENVARC:, because unused files in it will
  not be copied to ENV:

HappyENV should run on every Amiga(TM).


New since last release:
* Mixed read/write with one filehandle possible
* SetFileSize() now supported, fixes a nasty bug with SetEnv
* Startup options and new MountENV
