459
460VOWEL is a vowel string (e.g. \"\e(1`Q]P\e(B\").
461
462NO-MAA-SAKOD-RULE is a rule to re-order and modify VOWEL following a
463consonant. It is a list vowel characters or 0. The element 0
464indicate the place to embed a consonant.
465
466Optional WITH-MAA-SAKOD-RULE is a rule to re-order and modify VOWEL
467follwoing a consonant and preceding a maa-sakod character. If it is
468nil, NO-MAA-SAKOD-RULE is used. The maa-sakod character is alwasy
469appended at the tail.
470
471For instance, rule `(\"\e(1`WM\e(B\" (?\e(1`\e(B t ?\e(1W\e(B ?\e(1M\e(B))' tells that this vowel
472string following a consonant `\e(1!\e(B' should be re-ordered as \"\e(1`!WM\e(B\".
