/*
 * These are the currently planned wizard pages:
 *
 * o == interactive
 * . == automatic (no gui - none implemented currently)
 *
 * * = done
 * - = code here, but disabled in build
 *
 * --- THE LIST
 * o *ask for language (default selection is current locale).
 * o *ask for initial profile
 * o *find XDG app menus/repositories and list them let user choose which
 *    one(s) are to be used.
 * o -ask for ibar initial app set
 * o -ask if user wants desktop icons or not (enable fwin module but seed it
 *    with default config icons on desktop and favorites).
 * o -ask click to focus or sloppy
 * . *take some of current config (language, fileman, profile) and load
 *    load profile, apply language to it and save, restart e.
 *
 * why are some disabled? profiels take care of this and do a better job
 * at collecting all the things together. for example illume makes no sense
 * with pointer focus and ibar icons/desktop makes no sense.
