Mac OS/X Installation Tools
By tradition there are two ways to install software on OS/X: either drag-n-drop or by creating a package installer using the Apple tool. Both are normally delivered using a .dmg (disk image) file. Drag-n-drop typically is used when the program is self-contained and doesn't have many dependencies that are not normally found in the base OS/X setup.
Currently Chandler uses drag-n-drop but with the goal of using the native python installation, the focus will have to shift to using the package tool. This also has some beneficial side-effects: pre-install license prompts, pre-install checks, post-install prompts, etc.
