10..SYNOPSIS
11.Starts a list of physical machines by using Wake On LAN.
12. 
13..DESCRIPTION
14.WakeUp-Machines starts a list of servers using Wake On LAN magic packets. It then sends echo requests to verify that the machine has TCP/IP connectivity. It waits for a specified amount of echo replies before starting the next machine in the list.
15. 
16..PARAMETER Machines
17.The name of the file containing the machines to wake.
18. 
19..PARAMETER TimeOut
20.The number of seconds to wait for an echo reply before continuing with the next machine.
21. 
22..PARAMETER Repeat
23.The number of echo requests to send before continuing with the next machine.

37..NOTES
38.Make sure the MAC addresses supplied don't contain "-" or ".".
39. 
40.The CSV file with machines must be outlined using Name, MAC Address and IP Address with the first line being Name,MacAddress,IpAddress.
41.See below for an example of a properly formatted CSV file.
