+%Note (for those who use jbmacros):
+%  (a) the enumsentence macro is very similar to the \example command
+% in jbmacros; however, it does not have the annoying habit of leaving
+% the example number on one page and the example on the next (some
+% jbmacros don't have this problem). The eenumsentence macro is very
+% similar to the \examples macro.
+%  (b) \ex may be different
+
+% the enumsentence macro.
+%
+% \enumsentence{This is an example}
+% produces
+%  (1) This is an example
+% while
+% \enumsentence[(a)]{This is another example}
+% produces
+%  (a) This is another example
+% 
+% A related macros is 
+% \eenumsentence{\item[a.] A third example
+%                  \item[b.] A fourth example}
+% which produces
+%  (2) a. A third example
+%      b. A fourth example
+% 
+% other macro is \ex{1} which produces the number of the following
+% enumsentence (\ex{0} produces number of preceeding enumsentence and
+% so on.)
+% 
+% The standard \label command also works within \enumsentence and
+% \eenumsentence. 
+%
+% the \enumsentence counter.  Add [chapter] if using report style
+\newcounter{enums}
+
+% \widelabel is defined for use when the width of the enumsentence or
+% eenumsentence number is wider than 20pt (default labelwidth).  As a
+% rule of thumb if your enumerated sentences are only 1 or 2 digit
+% you don't need to worry.  At 3 digits, set \widelabel to 2.78pt at 4
+% digits set to 7.78pt.
