This is a skeletal packages hierarchy that will (eventually) be installed if it doesn't already exist. Installing XEmacs packages into this directory in the build area is a mistake. Subdirectories: etc/ This directory is added to the data-directory-list and is used for storing data files needed by Lisp packages at run-time. This includes things like image files, sound files, etc. info/ This directory is added to the Info-default-directory-list and is used for storing info documentation meant to be accessed when the user hits `C-h i'. lisp/ This directory and all its subdirectories are added recursively to the `load-path' at dump time. All auto-autoloads.el files found are dumped with XEmacs.
