It might be worth summarizing in a few lines what the proposal is.

My reading of it of pull/2475 is that the build tools used to generate 
source files, resources, or other files for the lib directory are moved 
into src/$MODULE/share/tools. I assume this is compatible with the 
source paths that the idea.sh script emits so it won't get confused with 
the source code for the module.

There are a couple of tools that digest data files imported from 
upstream to create source files and resources for more than one module 
and they aren't moving at this time, right? There is also the checked in 
jdwp.spec that is processed by a tool at build time to generate sources 
for 2 modules, that one might be a bit awkward too.

Are there any other high-level points that we should know about?
