OK.  Any chance Camm could support on this by implementing
read-sequence  in GCL?  Perhaps it isn't so critical if we're close to
running on SBCL in any case.

If everything works as it should, changing cl-web to LaTeX chunk style
should be as simple as changing this:

<<tangle-delimiter-variables>>=
(eval-when (:compile-toplevel :load-toplevel :execute)
  (progn
    (defvar chunk-start-delimiter "<<")
    (defvar chunk-name-end-delimiter ">>=")
    (defvar chunk-ref-start-delimiter "<<")
    (defvar chunk-ref-end-delimiter ">>")
    (defvar chunk-end-delimiter "@")))

@

to this:

<<tangle-delimiter-variables>>=
(eval-when (:compile-toplevel :load-toplevel :execute)
  (progn
    (defvar chunk-start-delimiter "\begin{chunk}{")
    (defvar chunk-name-end-delimiter "}")
    (defvar chunk-ref-start-delimiter "\chunk{")
    (defvar chunk-ref-end-delimiter "}")
    (defvar chunk-end-delimiter "\end{chunk}")))

and recompiling the cl-web file.

Did you want to incorporate that into the cl-web file?  How serious is
the breakage?  If we can shoe-horn together some kind of read function
that outputs what cl-web needs (even if it's slower) would the rest of
it work?

Nice!

That would be great.  In that case, should we bother with implementing
the conversion to LaTeX or just wait for the new style to roll out?

I'm interested in some of the possibilities having a (fast) tangle in
lisp opens up on the editor side, perhaps using Climacs or Able.  Emacs
seems to be showing its age when it comes to this type of editing, so
perhaps the better direction would be to focus on creating the exact
tool we need.  For the future, but interesting.

P.S.  I sent cl-web-v0.5 to the list, but it hit the filesize limit -
anybody know who the list admin is?
