## What it is
A Go library and CLI tool for creating and extracting archives (tar, zip, rar, 7z) and compressing/decompressing files (gzip, xz, bzip2, zstd, lz4, brotli, snappy) with a unified streaming API. It is deprecated and superseded by mholt/archives.

## Use cases
- extract a zip or tar archive in Go
- compress files to gzip or zstd from the command line
- create archives programmatically in Go
- identify archive format by filename or stream headers
- walk archive contents as a virtual file system

## When to choose
- maintaining legacy Go code already importing archiver v3 or earlier
- you need its specific CLI behavior and cannot migrate yet

## When to avoid
- starting a new Go project - use mholt/archives instead
- you need bug fixes or new features, since development has stopped

## Facets
- artifact type: library
- maturity: abandoned
- function: compression, file-system, cli
- domain: files, developer-tools, cross-platform
- platform: go, cross-platform, cli
- tags: archive-extraction, tar, zip, gzip, rar, 7zip, streaming, deprecated, successor-mholt-archives
