One command for zip, 7z, tar.*, ISO, RAR and its own .cram format: list, extract, create, test, mount, sign.
It uses every core, which most archivers don't. Creating 2.8GB / 42,151 files: 6.95s against 7-Zip's 68.25s, 13.4% smaller. A .zip extracts in 1.89s against 7.21s.
.cram stores repeated data once across files, not just whole duplicates.
Where it loses: little duplication means 9-19% larger than 7-Zip, and it costs memory. The corpus is a public download.
