This awesome appl' will simultaneously remove foreign language "localization" files AND remove extraneous PPC OR Universal Intel code from your applications. The only drawback is that you have to do it one application at a time.
Monolingual will do that, but AFAIK, it does it all at once, e.g., running one app at a time is unnecessary.
NOTE! If you strip the universal code to make it just PPC, and later buy an Intel machine, you may experience problems should you run the Migration Assistant, e.g., the data you migrated to your (new) Intel machine may be lacking the requisite Universal code (as it has been stripped) At least that's my understanding.
That all said, I believe
TinkerTool system v1.6 will purge localizations and allow stripping one app at a time.
Either way, Flash's counsel is worthy of merit and worth considering (IMNHO).
