* HTTPRanger * Migrate eestream library to use ReadCloser instead of Reader * Use MultiReadCloser instead of MultiReader * Adapt example cli cmds to latest serverbox changes * Close LazyReadCloser only if only generated * Close ReadClosers sequentially * Close response body on unexpected status code * Avoid double close of the pipe reader * Better formatting for imports * Exit instead of panicking
