[Insight-developers] ITKv4 Modularization Plan

[Bill Lorensen]

I understand the packaging argument, but why can't the tree names be
similar to what I proposed.

On linux, the packages have names like
gnome-disk-utility.i686

But, the tree names are conventional linux tree names.

I can't find any example on my linux distribution that uses a naming
convention like the one proposed.
