Customizing Maxima. Renaming Maxima functions

try
:lisp (setf (symbol-function '$rsum)(symbol-function '$integrate))
:lisp (unintern '$integrate)


While this accomplishes what you asked for, it is unlikely that this
makes sense for you to do.

Oh, you can restore the name by ..

:lisp (setf (symbol-function '$integrate) (symbol-function '$rsum))

This will not work for items in Maxima that are more than functions.
For example, $cos has various property that would have to be moved if
you renamed it $cosinus.

There is also a command called alias( ..)
