## プロジェクトの歴史と使われ方

RATS, the Rough Auditing Tool for Security, is a command-line static analysis scanner for finding common security-sensitive programming patterns in source code.

### プロジェクトの歴史

The official README says RATS was developed, maintained, and distributed by Secure Software, Inc. The 2.4 source archive describes it as a scanner for C, C++, Perl, PHP, Python, and Ruby source that flags issues such as buffer overflows and TOCTOU race conditions.

### 採用の歴史

RATS circulated as a small Unix security-auditing utility through source archives and package managers. Homebrew, Debian-derived manpage packaging, Fedora, MacPorts, and other Unix package collections carried it as a lightweight source-code auditing tool.

### 使われ方

Users run rats against files or directories and can select vulnerability databases with -d, force a language with -l, choose warning levels, recurse through directories, and emit text, XML, or HTML reports.

### パッケージ好きにとっての重要性

Package maintainers care about RATS because it is an old-style security CLI: small C code, autoconf build, XML vulnerability databases, and a package surface that exposes static-analysis behavior without a large framework.

### タイムライン

- 2001: The bundled manpage date records RATS documentation in September 2001.
- 2.4: Homebrew packages the Google Code archive release as the stable version.

### Related projects

- The README notes Expat as a build/runtime requirement and credits Ben Laurie for OpenSSL-specific database contributions.

### ソース

- Google Code Archive: official rough-auditing-tool-for-security project and source download.
- Homebrew formula metadata for rats stable 2.4.
- RATS 2.4 README and rats.1 from the official Google Code archive tarball.
