/*
 *   Master Configuration routines.
 *  
 *   This file contains the common parts of the Bacula
 *   configuration routines.
 *
 *   Note, the configuration file parser consists of three parts
 *
 *   1. The generic lexical scanner in lib/lex.c and lib/lex.h
 *
 *   2. The generic config  scanner in lib/parse_conf.c and 
 *    lib/parse_conf.h.
 *    These files contain the parser code, some utility
 *    routines, and the common store routines (name, int,
 *    string, time, int64, size, ...).
 *
 *   3. The daemon specific file, which contains the Resource
 *    definitions as well as any specific store routines
 *    for the resource records.
 *
 *    N.B. This is a two pass parser, so if you malloc() a string
 *         in a "store" routine, you must ensure to do it during
 *       only one of the two passes, or to free it between.
 *       Also, note that the resource record is malloced and
 *       saved in save_resource() during pass 1.  Anything that
 *       you want saved after pass two (e.g. resource pointers)
 *       must explicitly be done in save_resource. Take a look
 *       at the Job resource in src/dird/dird_conf.c to see how
 *       it is done.
