Subject: [toronto-lisp] LaTex for Scheme
Do any of you use LaTeX?
I am looking for something to typeset Scheme snippets in LaTeX article or amsart. I have tried slatex with so-so results. I am not happy to have to run it from the command line, and do not presently have time to hook it into emacs the way I want.
I use the listings package successfully for CL but this package does not really understand Scheme as far as I can tell.
