| 22 | * @brief Global configurations, initialized to configured defaults.
|
|---|
| 23 | *
|
|---|
| 24 | * This file should be the only file that depends on path
|
|---|
| 25 | * configuration (--prefix, etc), so that if ./configure is re-run,
|
|---|
| 26 | * all programs will be appropriately updated. Everything else in
|
|---|
| 27 | * Samba should import extern variables from here, rather than relying
|
|---|
| 28 | * on preprocessor macros.
|
|---|
| 29 | *
|
|---|
| 30 | * Eventually some of these may become even more variable, so that
|
|---|
| 31 | * they can for example consistently be set across the whole of Samba
|
|---|
| 32 | * by command-line parameters, config file entries, or environment
|
|---|
| 33 | * variables.
|
|---|
| 34 | *
|
|---|
| 35 | * @todo Perhaps eventually these should be merged into the parameter
|
|---|
| 36 | * table? There's kind of a chicken-and-egg situation there...
