+=head2 DATA FORMATS
+
+Each configuration parameter has a "conftype", as assigned in
+C<common-src/conffile.c>. The translation of most of these types into Perl
+values is straightforward:
+
+ CONFTYPE_INT Math::BigInt
+ CONFTYPE_INT64 Math::BigInt
+ CONFTYPE_REAL floating-point value
+ CONFTYPE_STR string
+ CONFTYPE_IDENT string
+ CONFTYPE_TIME Math::BigInt (epoch value)
+ CONFTYPE_SIZE Math::BigInt
+ CONFTYPE_BOOLEAN Math::BigInt
+ CONFTYPE_COMPRESS Math::BigInt
+ CONFTYPE_ENCRYPT Math::BigInt
+ CONFTYPE_HOLDING Math::BigInt
+ CONFTYPE_ESTIMATELIST [ Math::BigInt, .. ]
+ CONFTYPE_STRATEGY Math::BigInt
+ CONFTYPE_TAPERALGO Math::BigInt
+ CONFTYPE_PRIORITY Math::BigInt
+ CONFTYPE_RATE float, float
+ CONFTYPE_INTRANGE Math::BigInt, Math::BigInt
+ CONFTYPE_APPLICATION string
+ CONFTYPE_EXECUTE_ON string
+ CONFTYPE_EXECUTE_WHERE Math::BigInt
+ CONFTYPE_SEND_AMREPORT_ON Math::BigInt
+ CONFTYPE_IDENTLIST [ string, .. ]
+
+Note that C<CONFTYPE_INTRANGE> and C<CONFTYPE_RATE> each return two values, not
+an array reference.
+
+Include and exclude lists with type C<CONFTYPE_EXINCLUDE> return a hash giving
+all listed filenames (in the C<list> key), include/exclude files (C<files>),
+and a boolean indicating that the list is optional (C<optional>):
+
+ { list => [ str, .. ], file => [ str, .. ], optional => Math::BigInt }
+
+Properties are represented as a hash of hashes. The keys are the property
+names, converted to ASCII lowercase. Each property has a C<values> array
+giving all values specified for this property, as well as booleans C<priority>
+and C<append> that are true if the corresponding keyword was supplied.
+
+ { prop1 => { values => [ str, .. ] priority => int, append => int },
+ prop2 => { .. } .. }
+
+Note that integer types of all sizes become C<Math::BigInt> objects rather than
+Perl integers, as is the habit throughout Amanda.
+
+The C<CNF_AUTOLABEL> value is a hash with the following keys
+
+ template label template, or undef
+ other_config boolean
+ non_amanda boolean
+ volume_error boolean
+ empty boolean
