" Vim syntax file
" Language:     AsciiDoc
" Author:       Stuart Rackham <srackham@gmail.com> (inspired by Felix
"               Obenhuber's original asciidoc.vim script).
" URL:          http://asciidoc.org/
" Licence:      GPL (http://www.gnu.org)
" Remarks:      Vim 6 or greater
" Limitations:
" 
" - Nested quoted text formatting is highlighted according to the outer
"   format.
" - If a closing Example Block delimiter may be mistaken for a title
"   underline. A workaround is to insert a blank line before the closing
"   delimiter.
" - Lines within a paragraph starting with equals characters are
"   highlighted as single-line titles.
" - Lines within a paragraph beginning with a period are highlighted as
"   block titles.
