[plt-scheme] Updating PLaneT distributed tools: any conflicts?

Hi everyone,

I'm planning to make a point release of DivaScheme to push another few bug 
fixes we've made recently.  (As well as a feature to cooperate with 
DrScheme's automatic open-paren fixup thing.  Hurrah!)

One thing I was wondering, though: how does DrScheme choose which version 
of a PLaneT-distributed tool to load?

Assuming that there are several versions of that tool already installed in 
the local cache, does DrScheme always go for the highest version for each 
tool, or does it instead choose the one most-recently configured by 

I'm concerned that for people who already have DivaScheme (PLaneT package 
1.0) release installed, the presence of that old version might interfere 
with any new releases.  Regardless, it should be easy to address:  I can 
just write a quick uninstaller program that tells PLaneT to wipe older 
versions of DivaScheme.  Still, I'm curious what the official policy of 
this is.
