From the developer:
XX transforms files through a predefined succession of 'find/replace' commands. The idea builds on Xsed. But in contrast to Unix sed Xsed is not a true 'stream editor' - it loads files and then performs the requested transformation. So there's really no reason to not perform a succession of transformations if that's what's needed.
