I am using the standard importer, I think (I never overloaded any import function). At the beginning of NETWORK::SNMP, I have the following code (periods represent omitted code):

require Exporter;

@EXPORT=qw(@chassistypes $commstring $sysname $syscontact $syslocation
+ $ipadentaddr
        $cdpdevicecacheport $ipadentnetmask $cdpcacheplatform $cdpcach
+edeviceport
        $chassisid $chassistype $sysdesc $romid);
........

$commstring=`/usr/bin/cat /var/scripts/.data/commstring`;
chomp $commstring;

........

The following code appears in NETWORK::Discovery:

package NETWORK::Discovery;

use NETWORK::SNMP;
use Net::SNMP;
use Net::Ping;


sub new {
...
}

sub discover_pvp {
...
}

sub getnext_device {
....
}

sub getnext_nonsnmp {
...
}
