=head1 NAME

SQL::Translator::Parser::DBI::SQLite - parser for DBD::SQLite

=head1 SYNOPSIS

See SQL::Translator::Parser::DBI.

=head1 DESCRIPTION

Queries the "sqlite_master" table for schema definition.  The schema
is held in this table simply as CREATE statements for the database
objects, so it really just builds up a string of all these and passes
the result to the regular SQLite parser.  Therefore there is no gain 
(at least in performance) to using this module over simply dumping the 
schema to a text file and parsing that.
