| 21 | /* How this works: |
| 22 | |
| 23 | Fdump_emacs dumps everything up to my_edata as text space (pure). |
| 24 | |
| 25 | The files of Emacs are written so as to have no initialized |
| 26 | data that can ever need to be altered except at the first startup. |
| 27 | This is so that those words can be dumped as sharable text. |
| 28 | |
| 29 | It is not possible to exercise such control over library files. |
| 30 | So it is necessary to refrain from making their data areas shared. |
| 31 | Therefore, this file is loaded following all the files of Emacs |
| 32 | but before library files. |
| 33 | As a result, the symbol my_edata indicates the point |
| 34 | in data space between data coming from Emacs and data |
| 35 | coming from libraries. |
