+#   % replace
+#       The replace element is quite important, but a bit tricky.  In
+#       English (and probably other languages), one of the abbreviations
+#       for the word month that would be nice is "m".  The problem is that
+#       "m" matches the "m" in "minute" which causes the string to be
+#       improperly matched in some cases.  Hence, the list of abbreviations
+#       for month is given as:
+#         "mon month months"
+#       In order to allow you to enter "m", replacements can be done.
+#       $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

+#
+#   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
+#   create a back reference.
+#
+# ***NOTE*** Every hash element (unless otherwise noted) MUST be defined in
+# every language.
