Hi Tim
Near the end of parse_dsn()'s write up, $driver_dsn should be $driver.
Um, I don't think so:
=item C<parse_dsn>
($scheme, $driver, $attr_string, $attr_hash, $driver_dsn) = DBI->parse_dsn($dsn)
or die "Can't parse DBI DSN '$dsn'";
Breaks apart a DBI Data Source Name (DSN) and returns the individual
parts. If $dsn doesn't contain a valid DSN then parse_dsn() returns
an empty list.
$scheme is the first part of the DSN and is currently always 'dbi'.
$driver is the driver name, possibly defaulted to $ENV{DBI_DRIVER},
and may be undefined. $attr_string is the optional attribute string,
which may be undefined. If $attr_string is true then $attr_hash
is a reference to a hash containing the parsed attribute names and
=> values. $driver_dsn is the last part of the DBI DSN string.

The existence of $dsn, $driver, and $driver_dsn is a little confusing.
I've changed it to read:
=item C<parse_dsn>
($scheme, $driver, $attr_string, $attr_hash, $driver_dsn) = DBI->parse_dsn($dsn)
or die "Can't parse DBI DSN '$dsn'";

$scheme is the first part of the DSN and is currently always 'dbi'.
$driver is the driver name, possibly defaulted to $ENV{DBI_DRIVER},
and may be undefined. $attr_string is the contents of the optional attribute
string, which may be undefined. If $attr_string is not empty then $attr_hash
is a reference to a hash containing the parsed attribute names and values.
$driver_dsn is the last part of the DBI DSN string. For example:
($scheme, $driver, $attr_string, $attr_hash, $driver_dsn)
= DBI->parse_dsn("DBI:MyDriver(RaiseError=>1):db=test;port=42");
$scheme = 'dbi';
$driver = 'MyDriver';
$attr_string = 'RaiseError=>1';
$attr_hash = { 'RaiseError' => '1' };
$driver_dsn = 'db=test;port=42';

Thanks.
