                     23: 
                     24:  Fdump_emacs dumps everything up to my_edata as text space (pure).
                     25: 
                     26:  The files of Emacs are written so as to have no initialized
                     27:  data that can ever need to be altered except at the first startup.
                     28:  This is so that those words can be dumped as sharable text.
                     29: 
                     30:  It is not possible to exercise such control over library files.
                     31:  So it is necessary to refrain from making their data areas shared.
                     32:  Therefore, this file is loaded following all the files of Emacs
                     33:  but before library files.
                     34:  As a result, the symbol my_edata indicates the point
                     35:  in data space between data coming from Emacs and data
                     36:  coming from libraries.
