I won't presume to tell you how to do your job, because obviously you have more expertise than I (or I would be mg@gentoo.org), but since these little miscellaneous utilities are focused on specific attributes of the x windowing system, and seem to fit with those in x11-misc, I would suggest or inquire about moving them to x11-misc. At the very least, xtrlock and xlockmore are x screensavers that belong alongside x11-misc/xscreensaver. The other two I'm not quite as confident about, but I would appreciate at least a quick review. I chose not to file these as individual bug entries when I saw how closely related in potential genre and last committer each ebuild was. Much obliged -MG
tseng wanted it.
By instruction of tseng, I am moving all x* packages in app-misc to x11-misc. xearth, xtrlock and xsnap have been moved so far.
Done.
