-" Vim syntax file
-" Language: reStructuredText Documentation Format
-" Maintainer: Estienne Swart
-" URL: http://www.sanbi.ac.za/~estienne/vim/syntax/rest.vim
-" Latest Revision: 2004-04-26
-"
-" A reStructuredText syntax highlighting mode for vim.
-" (derived somewhat from Nikolai Weibull's <source@p...>
-" source)
-
-"TODO:
-" 0. Make sure that no syntax highlighting bleeding occurs!
-" 1. Need to fix up clusters and contains.
-" 2. Need to validate against restructured.txt.gz and tools/test.txt.
-" 3. Fixup superfluous matching.
-" 4. I need to figure out how to keep a running tally of the indentation in order
-" to enable block definitions, i.e. a block ends when its indentation drops
-" below that of the existing one.
-" 5. Define folding patterns for sections, etc.
-" 6. Setup a completion mode for target references to hyperlinks
-
-" Remove any old syntax stuff that was loaded (5.x) or quit when a syntax file
-" was already loaded (6.x).
