[developers] location of .sty files for LaTeX output from LKB?

[Ann Copestake]

do we have a standard location for .sty files with the appropriate
macros for the various types of LaTeX output from the LKB?  I think I
have appropriate local copies for the things I have defined, which I
will happily check in if they aren't to be found anywhere currently,
but I don't know where to find the macros for the mrs LaTeX output as
defined in mrs/basemrs.lisp

thanks

Ann
