=head1 NAME
Wiki::Toolkit::Setup::MySQL - Set up tables for a Wiki::Toolkit store in a MySQL database.
=head1 SYNOPSIS
use Wiki::Toolkit::Setup::MySQL;
Wiki::Toolkit::Setup::MySQL::setup($dbname, $dbuser, $dbpass, $dbhost);
Omit $dbhost if the database is local.
=head1 DESCRIPTION
Set up a MySQL database for use as a Wiki::Toolkit store.
=head1 FUNCTIONS
=over 4
=item B<setup>
use Wiki::Toolkit::Setup::MySQL;
Wiki::Toolkit::Setup::MySQL::setup($dbname, $dbuser, $dbpass, $dbhost);
or
Wiki::Toolkit::Setup::Mysql::setup( $dbh );
You can either provide an active database handle C<$dbh> or connection
parameters.
If you provide connection parameters the following arguments are
mandatory -- the database name, the username and the password. The
username must be able to create and drop tables in the database.
The $dbhost argument is optional -- omit it if the database is local.
B<NOTE:> If a table that the module wants to create already exists,
C<setup> will leave it alone. This means that you can safely run this
on an existing L<Wiki::Toolkit> database to bring the schema up to date
with the current L<Wiki::Toolkit> version. If you wish to completely start
again with a fresh database, run C<cleardb> first.

username must be able to drop tables in the database.
The $dbhost argument is optional -- omit if the database is local.
Clears out all L<Wiki::Toolkit> store tables from the database. B<NOTE>
that this will lose all your data; you probably only want to use this
for testing purposes or if you really screwed up somewhere. Note also
that it doesn't touch any L<Wiki::Toolkit> search backend tables; if you
have any of those in the same or a different database see either
L<Wiki::Toolkit::Setup::DBIxFTS> or L<Wiki::Toolkit::Setup::SII>, depending on
which search backend you're using.

=head1 ALTERNATIVE CALLING SYNTAX
As requested by Podmaster. Instead of passing arguments to the methods as
($dbname, $dbuser, $dbpass, $dbhost)
you can pass them as
( { dbname => $dbname,
dbuser => $dbuser,
dbpass => $dbpass,
dbhost => $dbhost
}
)
or indeed as
( { dbh => $dbh } )
Note that's a hashref, not a hash.
