## プロジェクトの歴史と使われ方

t2sz is a command-line compressor for seekable Zstandard output, with special handling for tar archives so individual tar members can be reached without decompressing the whole archive.

### プロジェクトの歴史

The README expands the name as tar to seekable zstd: a tar archive is compressed with each file in an independent Zstandard frame. GitHub repository metadata records the public repository creation in December 2020.

### 採用の歴史

The README advertises package-manager paths for AUR, Homebrew, Snap, Debian-style release packages, and source builds. The Homebrew input also records Alpine and Homebrew packaging, which fits a niche utility used by archive and compression users rather than a broad desktop audience.

### 使われ方

t2sz runs in tar mode for .tar input by default and raw mode for other files, accepts stdin and stdout, exposes compression-level and block-size controls, and produces output readable by ordinary Zstandard tools. Seeking benefits require companion readers such as libzstd-seek, indexed_zstd, or ratarmount.

### パッケージ好きにとっての重要性

Package nerds care because t2sz sits at the intersection of tar, zstd, random access, and archival ergonomics: it preserves standard decompression while adding structure that downstream tooling can exploit.

### タイムライン

- 2020: The public GitHub repository was created.
- 2026: GitHub releases show v1.2.x releases, with v1.2.5 published on 2026-03-08.
- 2026: The README documents Homebrew installation on Linux and macOS.

### Related projects

- The README names zstd, libzstd-seek, indexed_zstd, and ratarmount as related projects for compression and seekable reading.
