If you believe it is trash, remove it. It is trash only in that there 
was no follow-up. You and Walter seem to want everything in one bucket. 
In the past few days I have spent a lot of time on github using search 
to find out if there is a repository for an activity. So, if you feel it 
is correct, delete the sugaractivities trash.

The list of tries to clean up ASLO shows the problem. Each attempt 
started by trashing ASLO and beginning again. What is needed is to 
leverage what we have. I believe the first step is to make an up-to-date 
inventory of the Sugar activities and their status. That is my current 

Never is a long time.

"Rather than stuff
around with ASLO, we really need activity maintainers who will release
new activity versions."


Version numbers are treated in Sugar as text, so you are certainly 
correct. An activity version could be 'wonderful'.
However, the bundle browse-157.3.xo shows the version number. We could 
have myactivity-wonderful.xo.

This number by convention should be an integer incremented by a new 
release. This immediately informs the user that if the installed 
activity (List View) version number is less than the current version 
number on ASLO, there is a possible update. The original guidelines were 
to increment version numbers by 1.

Bundle deletion should never be done automatically. It requires a 
thoughtful decision. The decision to block Hello World illustrates our 
fundamental problem. We choose to 'deprecate' since it means the problem 
is no longer a problem and no further action is needed. Blocking Hello 
World doesn't seem much simpler than building a bundle by setup.py from 
the repository (after updating the version number to 7) and then 
installing in on ASLO. I know you are capable of both steps. Having a 
simple activity that users can refer to when attempting to build their 
own activity should be an essential part of our educational objective. 
Blocking does serve the purpose of eliminating the problem.
