Comment out a bunch of debugging statements which add a lot of noise to the console.

You might want to review these debugging statements. Some of them may be obsolete in which case they could be removed. Some of them may still be useful for the developer team, but then they should at least be disabled in the end user version. A few might even be useful for end users, in which case you may want to just keep them, but IMHO this should be kept to an absolute minimum -- like the legacy tcl warning which I kept so that the user can be made aware of issues with certain externals; I also put a comment in there which explains what this is about, so that proficient users can decide for themselves whether they want to comment this out.
