+# "mon month months"

+# $replace is a list of pairs of words which are matched and replaced
+# AS ENTIRE WORDS. Having $replace equal to "m"->"month" means that
+# the entire word "m" will be replaced with "month". This allows the
+# desired abbreviation to be used. Make sure that replace contains
+# an even number of words (i.e. all must be pairs). Any time a
+# desired abbreviation matches the start of any other, it has to go
+# here.
+#
+# $ exact exact mode exactly
+# $ approx approximate mode approximately
+# $ business business mode business
+#
+# r sephm hour/minute separator (?::)
+# r sepms minute/second separator (?::)
+# r sepss second/fraction separator (?:[.:])
+#
+# Elements marked with an asterix (@) are returned as a set of lists.
+# Each list contains the strings for each element. The first set is used
+# when the 7-bit ASCII (US) character set is wanted. The 2nd set is used
+# when an international character set is available. Both of the 1st two
+# sets should be complete (but the 2nd list can be left empty to force the
+# first set to be used always). The 3rd set and later can be partial sets
+# if desired.
+#
+# Elements marked with a dollar ($) are returned as a simple list of words.
+#
+# Elements marked with a percent (%) are returned as a hash list.
+#
+# Elements marked with (r) are regular expression elements which must not

+#
+# ***NOTE*** Every hash element (unless otherwise noted) MUST be defined in
