## プロジェクトの歴史と使われ方

Tofrodos is a small command-line text conversion package for moving files between DOS/Windows CRLF line endings and Unix LF line endings.

### プロジェクトの歴史

The upstream README describes Tofrodos as two programs, fromdos and todos, that convert ASCII and UTF-8 text files between DOS and Unix newline formats. It is intentionally portable across Unix-like systems, Windows consoles, and DOS-family environments.

The package keeps the older Unix utility convention of behavior-by-command-name: the same program can be installed or renamed as fromdos, todos, dos2unix, or unix2dos, and it chooses the conversion direction from the invoked name.

### 採用の歴史

The upstream documentation points Linux users to distribution repositories, and the package record shows it available through Homebrew, Debian, Ubuntu, and Fedora/DNF.

### 使われ方

Typical use is direct shell conversion of one or more text files, wildcard batches, or pipeline use such as converting output before comparing it with diff.

### パッケージ好きにとっての重要性

Tofrodos matters as a tiny packaging-era compatibility utility: it solves the recurring CRLF/LF problem without pulling in a larger editor or VCS workflow, and its fromdos/todos command names are easy to script.

### タイムライン

- Current: Distributed as fromdos and todos for DOS-to-Unix and Unix-to-DOS newline conversion.
- Current: Packaged by Homebrew, Debian, Ubuntu, and Fedora/DNF according to the input package-manager facts.

### Related projects

- dos2unix and unix2dos are related command names and behaviors explicitly supported by Tofrodos.
- The package belongs to the same niche as other newline-normalization tools used in cross-platform source trees.
