A while back, I was working on creating an installer for an in-house project using the Nullsoft installer (NSIS). It’s an interesting system but it’s a bit flaky in a couple of areas. One of these areas is installing and/or removing entire directory structures. It appears that the system is generally designed for explicit definitions of all directories and files. While this may often be a perfectly acceptable solution, I wanted a more dynamic system. Because I’ve been developing the installer externally to the actual development of the project, I don’t keep track of what files or directories need to be included, nor do those files and directories remain stable.
