 =head1 NAME
 
-SQL::Translator::Parser - base object for parsers
+SQL::Translator::Parser - describes how to write a parser
 
 =head1 DESCRIPTION
 
-Parser modules that get invoked by SQL::Translator need to implement
-a single function: B<parse>.  This function will be called by the
-SQL::Translator instance as $class::parse($data_as_string).  Other
-than that, the classes are free to define any helper functions, or
-use any design pattern internally that make the most sense.
+Parser modules that get invoked by SQL::Translator need to implement a
+single function: B<parse>.  This function will be called by the
+SQL::Translator instance as $class::parse($tr, $data_as_string), where
+$tr is a SQL::Translator instance.  Other than that, the classes are
+free to define any helper functions, or use any design pattern
+internally that make the most sense.
+
+When the parser has determined what exists, it will communicate the
+structure to the producer through the SQL::Translator::Schema object.
+This object can be retrieved from the translator (the first argument
+pass to B<parse>) by calling the B<schema> method:
+
+  my $schema = $tr->schema;
+
+The Schema object has methods for adding tables, fields, indices, etc.
+For more information, consult the docs for SQL::Translator::Schema and
+its related modules.  For examples of how this works, examine the
+source code for existing SQL::Translator::Parser::* modules.
