----------------------------------------
Added a *{{dev:show-tree}}* in
http://svn.apache.org/viewvc?view=revision&revision=887233
This can be used to represent bundle dependencies 'graphically' and it will
also warn users if multiple bundles in the dependency graph are exporting the
same packages.

> Fix For: karaf-1.4.0

>
> At development time, people sometimes bump into classloading or bundle
> resolution issues. Proposing to add a subshell with a few development tools
> that can be used to troubleshoot these issues:
> - To solve the "unable to resolve due to constraint violation", we could
> build a tool that discovers multiple bundles exporting the same package that
> are needed to resolve the given bundle to give people a clue which
> uses-constraints might be involved
> - To solve a CNFE, we could build a tool that takes a snapshot of imports,
> enabled dynamic imports and refreshes the bundle and then checks the imported
> packages again to see which imports were added by the dynamic import
