12.2 Overview

The portable dumping system has to:

1. At dump time, write all initialized, non-quickly-rebuildable data to a file [Note: currently named xemacs.dmp, but the name will change], along with all informations needed for the reloading.
2. When starting xemacs, reload the dump file, relocate it to its new starting address if needed, and reinitialize all pointers to this data. Also, rebuild all the quickly rebuildable data.
