`%clay` ======= Our filesystem. `%clay` is version-controlled, referentially-transparent, and global. While this filesystem is stored in `%clay`, it is mirrored to Unix for convenience. Unix tells `%clay`s whenever a file changes in the Unix copy of the filesystem so that the change may be applied. `%clay` tells unix whenever an app or vane changes the filesystem so that the change can be effected in Unix. Apps and vanes may use `%clay` to write to the filesystem, query it, and subscribe to changes in it. Ford and gall use `%clay` to serve up apps and web pages. `%clay` includes three components. First is the filesystem/version control algorithms, which are mostly defined in `++ze` and `++zu` in zuse. Second is the write, query, and subscription logic. Finally, there is the logic for communicating requests to, and receiving requests from, foreign ships.
