If the environment variable DBI_AUTOPROXY is defined (and the driver i
+n $data_source is not ``Proxy'') then the connect request will automa
+tically be changed to:
$ENV{DBI_AUTOPROXY};dsn=$data_source
DBI_AUTOPROXY is typically set as ``dbi:Proxy:hostname=...;port=...''.
+ If $ENV{DBI_AUTOPROXY} doesn't begin with 'dbi:' then ``dbi:Proxy:''
+ will be prepended to it first. See the DBD::Proxy documentation for
+more details.
