+T1/EC and UTF-8 encodings, mainly in modern spelling (u when u is needed and v
+when v is needed), medieval spelling with the ligatures @code{\\ae} and
+@code{\\oe} and the (uncial) lowercase 'v' written as a 'u' is also supported.
+Apparently there is no conflict between the patterns of modern Latin and those
+of medieval Latin.  It also includes hyphenation patterns for the Classical
+Latin in T1/EC and UTF-8 encodings.  Classical Latin hyphenation patterns are
+different from those of 'plain' Latin, the latter being more adapted to modern
+Latin.  It also provides hyphenation patterns for the Liturgical Latin in
+T1/EC and UTF-8 encodings.")
