 So not only can it convert lisp expressions to latex, it can also, give intermediate solution steps. Perfect for doing homeworks (as that's what I made it for) :P

+@itemize
+@item
+There are many tests to be written for the functions.
+@item
+Many functions that might have special syntax in @LaTeX{} yet to be written. For example @code{1+}, @code{defun} were added later (it only started with 4 operators), similar could be done for many more.
+@item
+Fixing some glitches with the current functions.
