Comment: Unfinished draft for X keyboard extension.

The X keyboard extension, or XKB, defines the way keyboards codes are handled in Xorg.

Dump current configuration:

$ xkbcomp $DISPLAY -

Print current components in a format accepted by xkbcomp:

$ setxkbmap -print

Load a configuration file from the current directory:

$ xkbcomp $DISPLAY -I. config.xkb $DISPLAY

The system-wide files are in /usr/share/X11/xkb/.

There are five components:

keycodes
Defines symbolic names for keycodes.
types
Defines key types.
compat
Internal behavior of modifiers.
symbols
Maps symbols to keycodes (by symbolic name).
geometry
Used to depict keyboard layouts (e.g. with xkeycaps or xorg-xkbprintAUR).

rules define how components are combined.
