=head1 PARSER OPTIONS
+=head2 dbic_schema
+
+The DBIx::Class schema (either an instance or a class name) to be parsed.
+This argument is in fact optional - instead one can supply it later at
+translation time as an argument to L<SQL::Translator/translate>. In
+other words both of the following invocations are valid and will produce
+conceptually identical output:
+
+ my $yaml = SQL::Translator->new(
+ parser => 'SQL::Translator::Parser::DBIx::Class',
+ parser_args => {
+ dbic_schema => $schema,
+ },
+ producer => 'SQL::Translator::Producer::YAML',
+ )->translate;
+
+ my $yaml = SQL::Translator->new(
+ parser => 'SQL::Translator::Parser::DBIx::Class',
+ producer => 'SQL::Translator::Producer::YAML',
+ )->translate(data => $schema);
+
=head2 add_fk_index
Create an index for each foreign key.
