+@node version in documentation files
+@section @code{\version} in documentation files
+
+Every documentation file which includes LilyPond code must begin
+with a @code{\version} statement, since the build procedure
+explicitly tests for its presence and will not continue otherwise.
+The @code{\version} statement should reference a version of LilyPond
+consistent with the syntax of the contained code.
+
+Since the @code{\version} statement is not valid Texinfo input it
+must be commented out like this:
+
+@example
+@@c \version "2.19.1"
+@end example
+
+So, if you are adding LilyPond code which is not consistent with the
+current version header, you should
+
+@enumerate
+
+@item
+run convert-ly on the file using the latest version of LilyPond
+(which should, if everybody has done proper maintenance, not change
+anything);
+
+@item
+add the new code;
+
+@item
+modify the version number to match the new code.

+@end enumerate
