29 * Main configuration file parser for Bacula User Agent
30 * some parts may be split into separate files such as
31 * the schedule configuration (sch_config.c).
33 * Note, the configuration file parser consists of three parts
35 * 1. The generic lexical scanner in lib/lex.c and lib/lex.h
37 * 2. The generic config scanner in lib/parse_config.c and
39 * These files contain the parser code, some utility
40 * routines, and the common store routines (name, int,
43 * 3. The daemon specific file, which contains the Resource
44 * definitions as well as any specific store routines
45 * for the resource records.
