+%%% The 'subexamples' environment

+% New in v1.6 (2018-09-07)
+% subexamples is an environment for displaying a series of examples
+%             that belong together and thus share an example number
+%             (with an alphabetic subcounter).  Usage:
+%
+%             \begin{subexamples}
+%             \item This is the first subexample.
+%             \item This is the second subexample.
+%             \end{subexamples}
