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