" Vim syntax file for Trac wiki syntax
"
" Language:     trac wiki
" Maintainer:   Caleb Constantine <cadamantine@gmail.com>
" Last Change:  22 Nov 2010
" Version: 0.5

" Modified extensively from wiki.vim, by Andreas Kneib,
" http://www.vim.org/scripts/script.php?script_id=725

" To use this syntax file:
"
" - Put the file in your syntax directory, e.g. ~/.vim/syntax,
"   $HOME/vimfiles/syntax (see :help syntax).
" - Enable file type detection. One method is to add the following to your
"   filetype.vim file, which is usually located in ~/.vim or $HOME/vimfiles
"   (create it if not present, see :help filetype):
"
"       augroup tracwiki
"           au! BufRead,BufNewFile *.tracwiki   setfiletype tracwiki
"       augroup END
"
" TODO: 
" - Highlight tables.
" - Highlight Blockquotes
" - Highlight Numbered (ordered) lists
" - Highlight Processors. Some processors can have there own syntax highlight,
"   e.g. rst. Pull in syntax for these from existing syntax files.
" - Some wiki formatting is allowed inside discussion citations
"   (tracDisussion). We don't currently support that but we should.


" Quit if syntax file is already loaded
if version < 600
