// Version 2.0

// The following variants are defined in this file:

// "bds" - the BDS keyboard layout compliant with the proposed
//         Bulgarian state standard BDS 5237:2006

// "bekl" - the „enhanced“ variant of the Bulgarian BDS keyboard,
//          proposed in May 2020.

// "phonetic" - the phonetic Bulgarian layout with the traditional position
//              of the letters

// "bas_phonetic" - the phonetic keyboard layout compliant with the
//                  proposed Bulgarian state standard BDS 5237:2006

// "latin" - an extended variant of the QWERTY layout with symbols that
//           Bulgarian users will type while the keyboard is in Latin mode

// The reasons behind the layout of the symbols in levels 3 and 4 are
// explained in http://arxiv.org/abs/0905.0484  (in Bulgarian).

// Two notes for the maintainers of xkeyboard-config:

// 1. Please do not use key names such as <LatQ> for the Bulgarian
// phonetic layouts.  The placement of the symbols must stay always
// the same regardless of which one of the alias sets in
// xkb/keycodes/aliases is used.

// 2. The layouts should not include level3(ralt_switch).

//////////////////////////////////////////////////////////////////////////

// Describes Bulgarian keyboard "BDS" according to the new state standard
// BDS 5237:2006 and extended with symbols in levels 3 and 4.
