Save the following DEFPACKAGE and DEFUN in a file, say, zz.lisp:
(defpackage :babu
(:use :common-lisp))
(defun babu::hello ()
(print "hello"))
In the same directory where you create zz.lisp, type the following into
a Unix shell:
lisp -quiet -noinit -nositeinit -eval '(progn (load "zz") (print (find-package
:babu)) (quit))'
and you'll get #<The BABU package, 1/9 internal, 0/2 external> printed out
on the screen.
If you type the following into a Unix shell:
lisp -quiet -noinit -nositeinit -eval '(progn (load "zz") (babu::hello) (quit))'
you get an error:
Reader error at 31 on #<String-Input Stream>:

What did I do wrong?
