Subject Re: Remove Version from File Names in Distributions; Add Manifest
Date Tue, 28 Jul 2015 14:51:41 GMT
The Tomcat example was the first thing that came to my mind.  What is your
use case that makes this problematic?  If symlinks are the main issue, why
not use your distribution's package manager instead?
