31 | ?X: This file ends up producing the config_h.SH script, which is run to produce |
| 32 | ?X: the config.h file. The file ./.Config_h below contains all the ?H: lines | |
| 33 | ?X: extracted out of all the units. Metaconfig itself adds the !GROK!THIS!. | |
| 34 | ?X: Note that this code isn't included into Configure, but must be shipped with. | |
| 35 | ?X: | |
| 36 | ?X: For those who wish to know why the file is config_h.SH instead of the more | |
| 37 | ?X: natural config.h.SH, well... it is to support systems like MS-DOG. Only one | |
| 38 | ?X: 'dot' is allowed within the file name, as it is part of the "extension" of | |
| 39 | ?X: the file. MS-DOG will not let you have two 'dots' because that would mean | |
| 40 | ?X: two "extensions". | |
