+ * Main configuration file parser for Bacula User Agent
+ * some parts may be split into separate files such as
+ * the schedule configuration (sch_config.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.
