23/**
24 * @file dynconfig.c
25 *
26 * @brief Global configurations, initialized to configured defaults.
27 *
28 * This file should be the only file that depends on path
29 * configuration (--prefix, etc), so that if ./configure is re-run,
30 * all programs will be appropriately updated. Everything else in
31 * Samba should import extern variables from here, rather than relying
32 * on preprocessor macros.
33 *
34 * Eventually some of these may become even more variable, so that
35 * they can for example consistently be set across the whole of Samba
36 * by command-line parameters, config file entries, or environment
37 * variables.
38 *
39 * @todo Perhaps eventually these should be merged into the parameter
40 * table? There's kind of a chicken-and-egg situation there...
