+%%% Description : Erlangish MarkDown To Erlangish XML
+%%%
+%%% Note that this script has *one and only one*
+%%% specific purpose. That purpose is to generate XML
+%%% that fits into the Erlang/OTP documentation, so that
+%%% the Erlang/OTP "readme" files also can be part of
+%%% the Erlang/OTP HTML and Erlang/OTP PDF
+%%% documentation. Nothing more, nothing less. It is
+%%% *not* intended as some kind of a generic Markdown to
+%%% XML tool, and never will be.
