2 * Main configuration file parser for Bacula User Agent
3 * some parts may be split into separate files such as
4 * the schedule configuration (sch_config.c).
6 * Note, the configuration file parser consists of three parts
8 * 1. The generic lexical scanner in lib/lex.c and lib/lex.h
10 * 2. The generic config scanner in lib/parse_config.c and
12 * These files contain the parser code, some utility
13 * routines, and the common store routines (name, int,
16 * 3. The daemon specific file, which contains the Resource
17 * definitions as well as any specific store routines
18 * for the resource records.
