#
# 1. Define the auxiliary functions db_default, regex_excape,
#    regex_pattern_escape and regex_unescape.
#
# 2. Define the function all_kbdnames listing all supported keyboard
#    models, layouts and variants and a function keyboard_present
#    testing whether the computer has at least one keyboard
#
# 3. Function ask_debconf.  Ask the user to choose amongst the options
#    listed in $kbdnames.
#
# 4. Function guess_arch - detect the architecture and subarchitecture
#
# 5. Function keyboard_present - test if the computer has at least one keyboard
#
# 6. Set $locale.  Extract the strings for the chosen language in $kbdnames.
#
# 7. Compute default values for $XKBMODEL, $XKBLAYOUT, $XKBVARIANT
#    based on the architecture and the locale.
#
# 8. Overwrite (some of) the computed default values by:
#    - preseeded values (for the udeb);
#    - the value of debian-installer/keymap
#    - the contents of /etc/X11/xorg.conf
#    - the settings in the configuration files (/etc/default/...).
#    - correct some bugs of previous versions of console-setup
#
# 9. If the computer doesn't have keyboard then do not ask questions,
#    simply store the default values in the configuration file.  This
#    is in order to support headless installs in d-i.  The regular
#    packages (console-setup and console-setup-mini) should not be
#    installed on such sistems.
#
# 10. Compute default values for the Debconf questions.  For example
#     from XKBLAYOUT=us,el we obtain debconf_layout=el and from
#     XKBOPTIONS=lv3:ralt_switch we obtain debconf_altgr='Right Alt (AltGr)'
#
# 11. Ask the Debconf questions starting from STATE=1.
