Help with Expect command to change config on hundreds of ASA's.

Question

Hi All,
I'm looking for some help with the Expect command to automate some tasks, I'm certainly no programmer but I am struggling, here is an example of my script.
#!/usr/bin/expect -f
# This simple Expect script will add a new Syslog destination in
# Cisco switches (IOS based)
# We assume here that all switches uses the same credentials
# for the administrative tasks
# Define variables
set password "site1"
set enablepassword "site1"
# Define all the switches to be reconfigured (separated by spaces)
set switches "site1 site2 site3"
# Main loop
foreach switch $switches {
        puts "Processing switch: $switch";
        # Open the telnet session:
        spawn telnet $switch
        # Perform authentication
        expect "Password:"
        send "$password\r"
        expect ">"
        # Switch to enable mode
        send "en\r"
        expect "Password:"
        send "$enablepassword\r"
        expect "#"
        # Enable configuration mode (terminal)
        send "conf t\r"
        expect "#"
        # Modify VLAN1
        send "interface vlan1\r"
        expect "#"
     # Change VLAN1 Description to Uppercase
        send "description INSIDE\r"
        expect "#"
        send "exit\r"
        expect "#"
        # Save config to NVRAM
        send "wr\r"
        expect "#"
        #Logging out
        send "exit\r"
        expect eof
In the example this works fine for SITE1 passing the credentials SITE1 as the default password and SITE1 as the enable password.  I need to do usernames and passwords that are different for each site.  I have to make some changes across hundreds of ASA's to terminating tunnels to a new location.  Can anyone help out in how to do this, I know I am close I just need it to read, siteA, username, both passwords from a text file, etc
