So which package will be favored if all of the following are available:



If last part "does not imply version", then they are all "flavors" of 
same version 23.2.7, yet one might be a bugfix of the other and the 
third a feature enhancement.

Also, if you permit local branches to add more version parts, are they 
then allowed to add yet another part if need be?  What is the strict 

Or do you not want a strict logic (now, but learn as you move on)?

And why a "more strict" part if it does not imply version?  And if it 
does get used to resolve which of multiple flavors win an election, what 
is then the sorting algorithm when you permit both capital and lowercase
