'man wpa_action' gives a hint as well:

       An example wpa_supplicant.conf configured to roam between 3
different networks:

              network={
                   ssid="foo"
                   id_str="uni"
                   key_mgmt=NONE
              }

              network={
                   ssid="bar"
                   id_str="home_static"
                   psk=123456789...
              }

              network={
                   ssid=""
                   key_mgmt=NONE
              }

       The  corresponding interfaces file would contain LOGICAL interfaces,
that correlate to each unique ’id_str’ provided by the configuration
file:

              iface eth1 inet manual
                   wpa-driver wext
                   wpa-roam /path/to/wpa_supplicant.conf

              iface default inet dhcp

              iface uni inet dhcp

              iface home_static inet static
                      address 192.168.0.20
                      netmask 255.255.255.0
                      network 192.168.0.0
                      broadcast 192.168.0.255
                      gateway 192.168.0.1
