7           use CPAN::Kwalify;
8           validate($schema_name, $data, $file, $doc);

10           =head1 DESCRIPTION
11            
12           =over
13            
14           =item _validate($schema_name, $data, $file, $doc)
15            
16           $schema_name is the name of a supported schema. Currently only
17           C is supported. $data is the data to be validated. $file
18           is the absolute path to the file the data are coming from. $doc is the
19           index of the document within $doc that is to be validated. The last
20           two arguments are only there for better error reporting.
21            
22           Relies on being called from within CPAN.pm.
23            
24           Dies if something fails. Does not return anything useful.
25            
26           =item yaml($schema_name)
27            
28           Returns the YAML text of that schema. Dies if something fails.
