# Define your Linode API key as $API_KEY_LINODE in api_keys.pm in the plugin library directory
#  a sample should be included in this distribution.
#
# This plugin requires WebService::Linode from CPAN, with a patch - add the following to the end of sub _error{} in Linode/Base.pm:
#  $self->{err} = $err; $self->{errstr} = $errstr;
# Also - bug in WebService::Linode::Base docs, example, line 3 should be:
#  my $data = $api->do_request( api_action => 'domains.list' );
# not:
#  my $data = $api->do_request( action => 'domains.list' );
