+# BGN/PCGN Agreement
+#
+# This system wad devised by G. M. McCune and E. O. Reischauer, and
+# was originally published in the Transactions of the Korea Branch of
+# the Royal Asiatic Society, Volume XXIX, 1939. It has been used by
+# the BGN since 1943, and was later adopted for use by the PCGN. A
+# main characteristic of this system is the attempt to represent
+# approximate Korean pronunciation, while systematically converting
+# the Hangul characters to corresponding Roman-script letters. Since
+# Korean pronunciation is often inconsistently represented in Hangul,
+# the McCune-Reischauer conversion tables are rather elaborate, and
+# reverse conversion (from Roman script back to Hangul) is not possible.
