+# BGN/PCGN 1962 System
+#
+# This system is a simplified version of the system devised by the PCGN
+# in 1941 and later adopted by the BGN. In 1962 the two organizations
+# agreed to joint adoption of certain changes in the original system,
+# specifically the omission of special rules for the treatment of Greek
+# geographic names of Albanian, Bulgarian, Italian, Macedonian, and
+# Turkish origin. That revision eliminated the need to consider the
+# origin of names and removed ambiguity from the romanization of Greek
+# expressions of possible non-Greek origin. This system is based on
+# the pronunciation of modern Greek and is not intended for use in
+# the romanization of classical Greek.
+#
+# The Greek Alphabet as defined by the BGN (Pages 29-31):

+#
+# The apostrophe and reversed apostrophe, on or the other of which is
+# written in Greek in front of all initial uppercase vowel characters,
+# above all initial lowercase vowel characters, and above the second
+# character of all initial two-vowel character sequences, should not
+# be romanized, e.g., Ἀθῆναι → Athínai, Ἠράκλειον → Iráklion,
+# Οἰνόφυτα → Oinófita. These apostrophes must be distinguished from
+# accent marks hen they occur together, e.g. Ἄβατον → Ávaton,
+# Ἤλια → Ília, Οἴτη → Oíti. The reversed apostrophe is sometimes found

+# Stress is shown in Greek by the use of the tilde or circumflex,
