DropScript is one of my favorite hacks. It's an application for
Mac OS X which lets you create new applications from any BSD
program which takes files as command line arguments. Typically,
these are scripts written in sh, perl, etc.
This is a shell script that automates the process of creating a
disk image. Works well, though this version doesn't offer any
options; it only creates read-only HFS+ images.
