Use Ant to Maintain Custom Framework Builds

I'm pretty new to Ant, so I'm thankful that a lot of other developers have examples and sample build files that I can use as a guide to learning Ant. After writing a few small build files, I wanted to tackle something a little more ambitious. I like to keep all the frameworks that I use up to date from their respective repositories, and, when deploying a new site or project, I will typically include the framework dependencies as a minimal include at the project root. This requires a bit of work, exporting and stripping out documentation, examples and tests from my local checkout of the framework files. As a learning objective, I decided to write an ant build file to maintain my own "nightly build" of each framework customized to carry only the core files.
