+ purify
+
+
+ When true, calls (in effect) purify before
+ saving the heap image. This moves certain objects that
+ are unlikely to become garbage to a special memory area
+ that is not scanned by the GC (since it is expected that
+ the GC wouldn't find anything to collect).
+
+
+
+
+
+ impurify
+
+
+ If true, calls (in effect) impurify before
+ saving the heap image. (If both :impurify
+ and :purify are true, first
+ impurify is done, and then purify.)
+
+
+ impurify moves objects in certain special memory
+ areas into the regular dynamic heap, where they will be scanned
+ by the GC.

+ mode
+
+
+ A number specifying the mode (permission bits) of the output file.

+
+
+ prepend-kernel
+
+ Specifies the file to prepend to the saved heap
+ image. A value of t means to prepend
+ the lisp kernel binary that the lisp started with.
+ Otherwise, the value of :prepend-kernel
+ should be a pathname designator for the file to be
+ prepended.
+
+
+ If the prepended file is execuatable, its execute
+ mode bits will be copied to the output file.
+
+
+ This argument can be used to prepend any kind of file to
+ the saved heap image. This can be useful in some special
+ cases.
