[gentoo-user] system audit

[J.A.H.]

Hi --- Is there a way to print all of the installed programs by category. I would like to know what development libraries and tools are installed and also what is installed that I never use.  Basically I want to remove everything not in use so that another upgrade will take less time. Once I remove a program, library, or something else, how will I know that there will be no affected dependencies. Also is there something which will reveal that an executable or library has never been used or infrequently used. I have not installed many packages outside the portage sandbox. Most packages that were installed outside portage were installed in a non-portage area within usr. Note: Why are there administration, laptop, and server related posts at gentoo-user and less at gentoo-admin or the other ones? The amount of emails at gentoo-user is too high volume IMO. Why not remove gentoo-user and instead add more lists like gentoo-install, or whatever else. The gentoo-user list is misleading since every user using gentoo is a user. It should be removed instead. --
