+
+	Say command comes in four variants: SM, SLM, NM and NLM.
+	Note: In script files, they are usually written as *SM.
+	The asterisk is ignored by the readLine function.
+
+	Each of them plays a voice file (if present) and/or shows a message
+	(if voice file not present or subtitles are enabled).
+
+	The difference between versions starting with "S" and "N" is that
+	the "N" version does not show talking animation.
+
+	The "L" versions are "blocking", i.e. they wait for the previous say command to finish.
+
+	If the line ends with "<!", it means the message continues to the next line.
+	Next line usually has "SM" (or other variant) repeated, but it does not have to.
+	Then we have the rest of the string to say (which is concatenated with the previous line)
+	and possibly the voice file or "<!" again.
