Let's finish this chapter with some projects that combine the strengths of AppleScript with the strengths of Unix scripting.
In the first project, you'll implement a couple of utility handlers, encode_URL and uppercase_text, that use the popular Python scripting language (included in Mac OS X) to perform basic text processing tasks. In the second project, you'll create a simple drag-and-drop applet that uses the Unix chmod command to modify file and folder permissions. In the final project, you'll use a third-party Unix tool, pdffonts, to extract font information from PDF files.
