[Openmcl-devel] save-application

[Mark H. David]

Yes, (save-application ... :prepend-kernel t) does the trick.

Doc could be improved.  The documentation for function save-application 
(http://openmcl.clozure.com/manual/chapter4.9.html#Saving-Applications) 
no information about prepend-kernel nor any other of these keyword args:

   (purify t)  impurify  (mode #o644)  prepend-kernel

The text of this chapter leading up to the function does, in retrospect, 
explain the wonders of prepending the kernel in a somewhat chatty and 
roundabout style while managing to never actually refer to the 
PREPEND-KERNEL arg by name.

Thanks!
