+" Vim syntax file
+" Language:	Lynx 2.7.1 style file
+" Maintainer:	Scott Bigham <dsb@cs.duke.edu>
+" Last Change:	2001 May 09
+
+" For version 5.x: Clear all syntax items
+" For version 6.x: Quit when a syntax file was already loaded
+if version < 600
+  syntax clear
+elseif exists("b:current_syntax")
+  finish
+endif
+
+" This setup is probably atypical for a syntax highlighting file, because
+" most of it is not really intended to be overrideable.  Instead, the
+" highlighting is supposed to correspond to the highlighting specified by
+" the .lss file entries themselves; ie. the "bold" keyword should be bold,
+" the "red" keyword should be red, and so forth.  The exceptions to this
+" are comments, of course, and the initial keyword identifying the affected
+" element, which will inherit the usual Identifier highlighting.
