Changes  view on Meta::CPAN

	Recognized ESH EZH ENG and SCHWA as phonetized variants of s z n 0 (no majuscule SCHWA, as in Azeri).
	Add curses to LIMITATIONS section docs.
	Table of chars of bépo was missing many base characters.

	EurKey++:
	  Clean up .kbdd file a bit.
	  Add phonetized variants on macron prefix key (add ESH EZH and SCHWA, but removes ‒ so add schwa manually on AltGr).
	    (To support this, add rules introducing ÉŸ and v with right hook).
	  Add hookish+mutiliated rules to the `―´ pair.  (Adds only ʮ - not enough to add ʄ - is it 3 modifiers???)
	  Now eng's are on macron+etc+phonetized (and n with long right leg appear on `).
	  Add solidus (overlays) to macron.
	  Exchange diacritic signs for combining ´ ` in Cyrillic (on double AltGr-' and on AltGr-' with '; 
	    now Vietnamese versions (which got into Wikipedia ?!) are
	    on Shift-ed keys, and "normal" acute and grave are on unshifted.
	  Add Azeri Əə to Ë=AltGr-e, and ditto mark 〃 to " on Copyright face (AltGr-minus).
	  Add promille ‰ on % on ring/dots face, primes ′,″ on '," on Math (AltGr-M) and ‡ on †=AltGr-" on macron/bar face.
	  Latin's diacritics prefix keys are available from Cyrillic after Shift-Space. 

0.05	Infrastructure to allow multiple decompositions extracted from the Unicode database.
	  (Currently only changes the order of (dotless) j with stroke.)
	Add SLANTED, APPROXIMATELY, ASYMPTOTICALLY, ALMOST to mutiliated.
