Loads into the image all appropriate files from the directory
patches in the directory determined by
*lispworks-directory*, and then loads the file
private-patches/load.lisp where load forms for any private patches may be placed. When the appropriate patches have successfully been loaded, the updated version of the image can be saved using save-image.
The system expects all patches to be loaded sequentially. If a patch is missing, there is a warning message. In this situation, it is advisable to contact Lisp Support to obtain a copy of the missing patch.
