=head1 NAME
CPAN::SQLite::DBI - DBI information for the CPAN::SQLite database
=head1 VERSION
version 0.211
=head1 DESCRIPTION
This module is used by L<CPAN::SQLite::Index> and
L<CPAN::SQLite::Search> to set up some basic database
information. It exports two variables:
=over 3
=item C<$tables>
This is a hash reference whose keys are the table names, with
corresponding values being hash references whose keys are the
columns of the table and values being the associated data types.
=item C<$dbh>
This is a L<DBI> database handle used to connect to the
database.
=back
The main method of this module is C<make>, which is used
to make the tables of the database.
