# Boot sequence:
#
# kdeinit is used to fork off processes which improves memory usage
# and startup time.
#
# * kdeinit starts the dcopserver and klauncher first.
# * Then kded is started. kded is responsible for keeping the sycoca
#   database up to date. When an up to date database is present it goes
#   into the background and the startup continues.
# * Then kdeinit starts kcminit. kcminit performs initialisation of
#   certain devices according to the user's settings
#
# * Then ksmserver is started which in turn starts
#   1) the window manager (kwin)
#   2) everything in $KDEDIR/share/autostart (kdesktop, kicker, etc.)
#   3) the rest of the session.

# The user's personal KDE directory is usually ~/.kde, but this setting
# may be overridden by setting KDEHOME.
