Just my 2 cents: AFAIK, only if you are developing a new software that requires a specific library (or some of them, like "opencv", for example, which might not have yet been pulled by any other package) , then, and only then, you might add them to "world". Then, when your software is ready, please ( ;-) ) create a package for distributing your work, with those libraries as dependencies, and remove them from "world", as they will be pulled in by such package. As already remembered on this thread, each case must be checked. Best regards, Francisco
