+# All text after a double hash (##) is considered a comment and is placed in

+#
+# All text after a single hash (#) is considered a comment and will be ignored.

+
+# This tag specifies the encoding used for all characters in the configuration
+# file that follow. The default is UTF-8 which is also the encoding used for all
