5872# The replace element is quite important, but a bit tricky. In
5873# English (and probably other languages), one of the abbreviations
5874# for the word month that would be nice is "m". The problem is that
5875# "m" matches the "m" in "minute" which causes the string to be
5876# improperly matched in some cases. Hence, the list of abbreviations
5877# for month is given as:
5878# "mon month months"
5879# In order to allow you to enter "m", replacements can be done.
5880# $replace is a list of pairs of words which are matched and replaced
5881# AS ENTIRE WORDS. Having $replace equal to "m"->"month" means that
5882# the entire word "m" will be replaced with "month". This allows the
5883# desired abbreviation to be used. Make sure that replace contains
5884# an even number of words (i.e. all must be pairs). Any time a
5885# desired abbreviation matches the start of any other, it has to go
5886# here.
5887#
5888# $ exact exact mode exactly
5889# $ approx approximate mode approximately
5890# $ business business mode business
5891#
5892# r sephm hour/minute separator (?::)
5893# r sepms minute/second separator (?::)
5894# r sepss second/fraction separator (?:[.:])
5895#
5896# Elements marked with an asterix (@) are returned as a set of lists.
5897# Each list contains the strings for each element. The first set is used
5898# when the 7-bit ASCII (US) character set is wanted. The 2nd set is used
5899# when an international character set is available. Both of the 1st two
