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.
You should call load-all-patches before starting the LispWorks IDE. Thus, you normally place the call to this function in your .lispworks file.
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.
