+# in order for "normal" developers not to have to install asciidoc (which
+# brings in a couple hundred MB of dependencies) we now include both the
+# user-manual.txt and a copy of the generated .html file in git
+#
+# in order to avoid unnecessary thrash with minor version differences, when
+# submitting patches to the user manual, only submit the changes to the .txt
+# file - the maintainer will recreate the .html.git file
