Grease does not try to solve all problems. We are not testing Sockets or HTTP clients. We don’t expect platforms to have standard SSL or graphics libraries. Its scope may grow over time, but for now we’re focusing on extending the functionality of the core classes defined in the ANSI standard (collections, exceptions, streams, blocks, etc.) and on other pieces of functionality that are critical to the Seaside project (e.g. random number generation and secure hashing).
