Vim syntax files for .lhs files using \begin{code} and \end{code}

[Nicholas Nethercote]

Hi,

The Vim syntax file for literate Haskell programs handles code lines that
begin with a '>' character fine.  But in GHC much of the code is defined
between "\begin{code}" and "\end{code}" pairs, and that shows up as one
giant comment.

Does anybody know where I might be able to obtain a Vim syntax file that
handles these constructs?  I made a feeble attempt myself, but Vim's
syntax highlighting language defeated me.

Thanks.
