Description
This module implements a subset of the YAML specification for use in reading and writing CPAN metadata
files like META.yml and MYMETA.yml. It should not be used for any other general YAML parsing or
generation task.
NOTE: META.yml (and MYMETA.yml) files should be UTF-8 encoded. Users are responsible for proper encoding
and decoding. In particular, the "read" and "write" methods do not support UTF-8 and should not be used.

or die CPAN::Meta::YAML->errstr;
# finding the metadata
$meta = $yaml->[0];
# writing a META file
$yaml_text = $yaml->write_string
or die CPAN::Meta::YAML->errstr;
