;; The public interface is tight.
;; It has to be, because user-code is evalled with this module.
;; ***It should also be clean, well defined, documented and reviewed***
;; To be reasonably safe, you probably do not want to use the TeX
;; backend anyway, but rather the PostScript backend. You may want
;; to run gs in a uml sandbox too.
