20 * @file dynconfig.c
21 *
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...
