maxima with asdf, slime compatibility, cl-user::run error at startup

Hello. I am new to maxima.

1) I'd prefer to use it as a library through asdf rather than run
another sbcl image (I am running stumpwm already). I found maxima.asd
under src/. so i guess it is indeed possible. Is my guess correct?

2) Also I'd like to know if maxima emacs mode is compatilble with slime.

3) Every time at startup, maxima complains about (cl-user::run)

--8<---------------cut here---------------start------------->8---
restarts (invokable by number or by possibly-abbreviated name):
  0: [MACSYMA-QUIT] Maxima top-level
  1: [CONTINUE    ] Ignore runtime option --eval "(cl-user::run)".
  2: [ABORT       ] Skip rest of --eval and --load options.
  3:                Skip to toplevel READ/EVAL/PRINT loop.
  4: [QUIT        ] Quit SBCL (calling #'QUIT, killing the process).
--8<---------------cut here---------------end--------------->8---

cl-user::run is invoked by the maxima start script /usr/local/bin/maxima
perhaps i should add '(in-package :cl-user)'?

Thank you.
