+% The command |\capitalizetitle| \DescribeMacro{\capitalizetitle} is a
+% command similar to |\capitalizewords|, except that words which have
+% been previously designated as ``lower-case words'' are not
+% capitalized (\eg prepositions, conjunctions, \etc). In all cases,
+% the first word of the string is
+% capitalized, even if it is on the lower-case word list. Words are
+% added to the lower-case word list with the commands
+% |\addlcword|\DescribeMacro{\addlcword}, in the case of a single word,
+% or with |\addlcwords|\DescribeMacro{\addlcwords}, in the case of
+% multiple (space-separated) words. Because the addition of many words
+% to the lower-case list can substantially slow-down the execution of
+% the |\capitalizetitle| command, the command
+% |\resetlcwords| \DescribeMacro{\resetlcwords} has been added to
+% allow the user to zero out the lower-case word list.
