+                        XKM File Format Description
+                                Version 15
+
+1. Introduction
+
+The XKM file format is the exchange format for XKB keyboard descriptions
+between the server and xkbcomp. Usually, the server forks off xkbcomp,
+xkbcomp compiles the XKM format from the given parameters.
+The resulting XKM file is put into a directory readable by the server and
+then parsed.
+
+The XKM format is little more than a binary dump of various XKB-specific
+structures and hence tied to the ABI of the server.
+
+                              ❧❧❧❧❧❧❧❧❧❧❧
+
+1.1 About this file format description
+
+This description was produced by analyzing the XKM parsing code. Parts of
+the file description present in the original format specification may be
+missing. This description thus cannot be a reference document for XKM
+implementations.
+
+No description of the meaning of the various fields is given here. Refer to
+the XKB protocol specification for more details.
+                              ❧❧❧❧❧❧❧❧❧❧❧
+
+2. Notations used in this document
+
+Notation for structures:
+
+┌───
+  Name of struct
+	name of field:		type or fixed value of field
+	name of field:		type or fixed value of field
+└───
+
+Data types are identical to those used in the X Protocol specification
+except where noted otherwise. Structs specific to XKM are prefixed with XKM,
+defines specific to the XKB protocol specification are prefixed with Xkb and
+their value is equivalent to that in the protocol specification.
+
+Multiple instances of a given type are denoted in the following form:
+	name of field:		LISTofFIELDTYPE
+
+Length specifiers for such fields are usually prefixed with num_. For
+example, a struct containing a num_foo of 8 and a 'foo' field contains 8
+structures of type 'foo'.
+
+Variable length padding is specified as pad(x), where x is the length of the
+data to be padded out to a multiple of 4 bytes. For example, given an x of
+10, pad(x) would be the remaining 2 bytes to pad the whole struct to 12
+bytes.
+
+A special notation is a variable content struct. In this case, the contents
+of the struct depend on the value of one or more specific fields.
+┌───
+  Name of struct
+	field:			type or fixed value of field
+	field:			type or fixed value of field
+	───
+	field ⇒ value 1
+	⇒
+		specific field:		type
+		specific field:		type
+	───
+        field ⇒ value 2
+	⇒
+		specific field:		type
+		specific field:		type
+└───
+This notation denotes that if field is of value 1, this struct contains the
+specific fields listed underneath value 1.
+
+                              ❧❧❧❧❧❧❧❧❧❧❧
+
+3. XKM Format
+
+The XKM format is a binary format with structs usually being padded to a
+multiple of 4 bytes. No provisions for endianess are provided, the parser is
+left to guess the endianess of the XKM file.
+
+                              ❧❧❧❧❧❧❧❧❧❧❧
+3.1 Common data types
+
+┌───
+  XKMCountedString
+	count:			CARD16
+	string:			count * CHAR
+	pad:			pad(count + 2)
+└───
+
+XKMCountedString is used for user-readable identifiers. Prime example are
+the level names and the section names ("complete", "evdev(inet)", etc.)
+
+┌───
+  XKMGroupBits:		CARD8
+	group1			0x1
+	group2			0x2
+	group3			0x4
+	group4			0x8

+3.2 Header and Table of Contents
+
+┌───
+  XKMHeader
+	version:		CARD8
+	identifier1:		'm'
+	identifier2:		'k'
+	idenfifier3:		'x'
+└───
+
+The XKM file format has a 4 byte header identifying the file and the XKM
+version. The header is followed by the table of contents indicating the
+sections present in this file.
+
+┌───
+  XKMFileInfo
+	type:			CARD8
+	min_keycode:		CARD8
+	max_keycode:		CARD8
+	num_sectioninfo:	CARD8
+	present:		CARD16
+	pad:			CARD16
+	sectioninfo:		LISTofXKMSectionInfo
+└───
+
+min_keycode and max_keycode specify the keycode range for this keyboard
+descriptions. The core protocol requires min_keycode always be equal to or
+greater than 8.
+
+┌───
+  XKMSectionInfo
+	type:			CARD16
+		XkmTypesIndex		0
+		XkmCompatMapIndex	1

+		XkmGeometryIndex	5
+		XkmVirtualModsIndex	6
+	format:			CARD16
+	size:			CARD16
+	offset:			CARD16
+└───
+
+Describes the section found in a chunk of a file. This struct is found
+_twice_ in the file per section, once as part of the XKMFileInfo, once at
+the beginning of the actual section (see offset).
+The type specifies the type of the section, the section is to be parsed
+according to this type.
+Size and offset specify the size in bytes and the offset into the file in
+bytes, respectively.
+
+3.3 Sections
+
+Each section resides at the offset specified in the XKMFileInfo sectioninfo.

+
+3.3.1 XKMTypes
+
+An XKMTypes section describes the key types defined in a layout. Roughly
+speaking, a key type defines how many levels a given key has and which
+modifiers change to a particular level.
