#
# 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 takes control of the rest of the startup sequence

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