This is a first version of a little tool manipulating _especially_ the
AES's environment.

Behavior under AES < 4.1:

simply showing $PATH and $HOME, e.g. as defined in MiNT.Cnf or any AES
environment setter. There is no way to change the environment.


Behavior under AES 4.1:

sample calls:

aesenv

       shows the whole environment of AES only, e.g. as defined in GEM.Cnf
       or N_AES.Cnf or as defined by GEM-init

aesenv TEST=FOO

       installs a new AES environment variable named TEST containing the
       string FOO

aesenv TEST=

       clears the contents of the AES environment variable TEST (but the
       string TEST= will stay in the AES's environment memory)
