 # Usage:
 #    Add the following to any *.test file:
 #      :
-#    set @message="This is a message example";
+#    let $message= <value>;
 #    --source include/show_msg.inc
 #      :
 #
+# Attention:
+#   - Please do not write any spaces between $message and the "=", because the
+#     assignment will not work.
+#   - Be careful with single quotes. They must be escaped like "''" or "\'".
+#
+# "include/show_msg80.inc" contains a detailed description and examples.
