-Built sources are also not compiled by default.  You must explicitly
-mention them in some other @samp{_SOURCES} variable for this to happen.
+@code{BUILT_SOURCES} is actually a bit of a misnomer, as any file which
+must be created early in the build process can be listed in this
+variable.
 
-Note that, in some cases, @code{BUILT_SOURCES} will work in somewhat
-surprising ways.  In order to get the built sources to work with
-automatic dependency tracking, the @file{Makefile} must depend on
-@code{$(BUILT_SOURCES)}.  This can cause these sources to be rebuilt at
-what might seem like funny times.
+A source file listed in @code{BUILT_SOURCES} is created before the other
+@code{all} targets are made.  However, such a source file is not
+compiled unless explicitly requested by mentioning it in some other
+@samp{_SOURCES} variable.
