" Vim syntax file for the D programming language (version 0.116).
"
" Language:	D
" Maintainer:	Jason Mills<jmills@cs.mun.ca>
" Last Change:	2005 Mar 09
" Version:	0.12
"
" 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
