arsd.archive

Provides LZMA (aka .xz) and .tar file read-only support. Combine to read .tar.xz files, or use in conjunction with other files to read other types of .tar files.

Also has a custom archive called arcz read and write support. It is designed to efficiently pack and randomly access large numbers of similar files. Unlike .zip files, it will do cross-file compression (meaning it can significantly shrink archives with several small but similar files), and unlike tar.gz files, it supports random access without decompressing the whole archive to get an individual file. It is designed for large numbers of small, similar files.
