Hi Luciano,

Yes that is one of my goals.

Currently I have a solution for distributing
Haver and Cuis (which is included in the Haver distribution):
http://haver.klix.ch/overview.html#starting-the-image
and:
https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse/haver/packaging/Distributor.pck.st


@At all:
*If there is demand for creating
redistributable applications, please tell me so*

I will describe what I have in mind and we can discuss it. (I am sure 
Dr.Ge. has that requirement)

The easy solution is to get the plugin integrated into the normal vm 
build process.
Then again, their Linux build was broken for some time, that's why I a 
choose a revision from
February 2021 for Haver.

Currently I can live with a manual build process
for the virtual machines, I do not intend to
change them more than once every quarter.

Ah, yes. Please see:
https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse

However it is not that easy, you have to file in
a big change-set to the base-image to make
environments work:
https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse/environments/coreChanges/CuisCoreEnvironmentSupport.cs.st

This change-set is handcrafted, because
some methods modify the compiler's interface
to global symbols. That means, during file in,
the newly filed-in methods are called
immediately after their installation to
compile the next method in the change set.

See:
https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse/environments/coreChanges/CuisCoreEnvironmentSupport.cs.st#L561

and:

https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse/environments/coreChanges/CuisCoreEnvironmentSupport.cs.st#L593

After filing in that change set, the remaining
packages are filed in:
https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse/haver/Haverize.pck.st#L28

These packages can not be installed in a
Cuis-image; it lacks environment support
and the package files contain syntax,
that can not be parsed by Cuis:
https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse/haver/modules/Modules.pck.st#L3638


In a nutshell and before Casey is tempted
to quote another Arlo Guthrie song:

Every Haver-image I distribute is created from
a clean Cuis-image by the aforementioned
Haverize-package.

Note to myself: Include this text in the documentation.
