+After any copyright header, there is a blank line, and the
+.Va rcsid
+for source files.
+Version control system ID tags should only exist once in a file
+(unlike this one).
+Non-C/C++ source files follow the above example, while C/C++ source files
+follow the below one.
+All VCS revision identification from files obtained from elsewhere should be
+maintained, including if there are multiple IDs showing a file's history.
+In general, keep the IDs in tact, including any `$'s.
+Most non-FreeBSD VCS IDs should be indented by a tab if in a comment.

 Kernel include files (i.e. sys/*.h) come first; normally, you'll need
 <sys/types.h>
 OR <sys/param.h>, but not both!  <sys/types.h> includes <sys/cdefs.h>,
