/*
* Main configuration file parser for Bacula Tray Monitor.
*
* Adapted from dird_conf.c
*
* 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_config.c and
* lib/parse_config.h.
* These files contain the parser code, some utility
* routines, and the common store routines (name, int,
* string).
*
* 3. The daemon specific file, which contains the Resource
* definitions as well as any specific store routines
* for the resource records.
