AppleScript to Open a New iTerm Window and bring it to the front

New-iTerm-Window.scpt

(* 
 * New-iTerm-Window.scpt
 * 
 * Intended for use with QuickSilver
 *  I mapped option-y to running this script to create
 *  a new iTerm window on the current workspace
 *
 * Based on much Googling - very little "original" code here

if isAppRunning("iTerm") then
	tell application "iTerm"
		set myterm to (make new terminal)
		tell myterm
			set mysession to (make new session at the end of sessions)
			tell mysession
				exec command "/bin/bash -l"
			end tell
		end tell
		activate
	end tell
else
	activate application "iTerm"
end if
