+" Vim syntax file for the D programming language (version 0.90).
+"
+" Language:     D
+" Maintainer:   Jason Mills<jmills@cs.mun.ca>
+" URL:
+" Last Change:  2004 May 21
+" Version:      0.8
+"
+" Options:
+"   d_comment_strings - set to highlight strings and numbers in comments
+"
+"   d_hl_operator_overload - set to highlight D's specially named functions
+"   that when overloaded implement unary and binary operators (e.g. cmp).
+"
+" Todo:
+"   - Allow user to set sync minlines
+"
+"   - Several keywords (namely, in and out) are both storage class and
+"   statements, depending on their context. Must use some matching to figure
+"   out which and highlight appropriately. For now I have made such keywords
+"   statements.
+"
+"   - Mark contents of the asm statement body as special
+"
+
+" Quit when a syntax file was already loaded
+if exists("b:current_syntax")
+  finish
