Pass variables to Ruby script via command line

I've installed RubyInstaller on Windows and I'm running IMAP Sync but I need to use it to sync hundreds of accounts. If I could pass these variables to it via command line I could automate the whole process better.

# Source server connection info.
SOURCE_NAME = 'username@example.com'
SOURCE_HOST = 'mail.example.com'
SOURCE_PORT = 143
SOURCE_SSL = false
SOURCE_USER = 'username'
SOURCE_PASS = 'password'

# Destination server connection info.
DEST_NAME = 'username@gmail.com'
DEST_HOST = 'imap.gmail.com'
DEST_PORT = 993
DEST_SSL = true
DEST_USER = 'username@gmail.com'
DEST_PASS = 'password'

Something like this:

ARGV.each do|a|
  puts "Argument: #{a}"
end

then

$ ./test.rb "test1 test2"

or

v1 = ARGV[0]
v2 = ARGV[1]
puts v1       #prints test1
puts v2       #prints test2
