-- cd to the current finder window folder in iTerm. Or drag a folder onto this script to cd to that folder in iTerm.
-- found this script in the comments of this article: http://www.macosxhints.com/article.php?story=20050924210643297

-- Instructions for use:
-- paste this script into Script Editor and save as an application to ~/Library/Scripts/Applications/Finder/cd to in iTerm
-- run via the AppleScript Menu item (http://www.apple.com/applescript/scriptmenu/)
-- Or better yet, Control-click and drag it to the top of a finder window so it appears in every finder window.
-- Activate it by clicking on it or dragging a folder onto it.

-- Another nice touch is to give the saved script the same icon as iTerm.
-- To do this, in the finder, Get info (Command-I) of both iTerm and this saved script.
-- Click the iTerm icon (it will highlight blue) and copy it by pressing Comand-C.
-- Click on this script's icon and paste by pressing Command-V.

-- Another way to give it the same icon as iTerm is to save the script as an application bundle (instead of an application),
--  then copy the icon by entering these commands in iTerm:
-- $ cd ~/Library/Scripts/Applications/Finder/cd\ to\ in\ iTerm.app/Contents/Resources/
-- $ rm droplet.icns
-- $ cp /Applications/iTerm.app/Contents/Resources/iTerm.icns droplet.icns
-- $ touch ~/Library/Scripts/Applications/Finder/cd\ to\ in\ iTerm.app
