configuration file:
The CONFIG file is an INI file with up to three sections:
[defaults] Sets equivalents of --arrays|-A and --aoh|-O.
[rules] Each entry is a YAML Path assigning --arrays|-A or --aoh|-O for
precise nodes.
[keys] Wherever --aoh=key (or -O key) or --aoh=deep (or -O deep), each
entry is treated as a record with an identity key. In order to
match RHS records to LHS records, a key must be known and is
identified on a YAML Path basis via this section. Where not
specified, the first attribute of the first record in the
Array-of-Hashes is presumed the identity key for all records in
the set.
input files:
Only one input file may be the - pseudo-file (read from STDIN). Because the
relative position of the two input files is important, this will not be
inferred; you must use - to indicate which document is read from STDIN.
It doesn't make any sense to compare multi-document files, so only single-
document files are supported.
