## プロジェクトの歴史と使われ方

cppp is a partial C preprocessor: it applies only the subset of conditional preprocessing decisions requested by the user.

### プロジェクトの歴史

The official page describes cppp as a focused tool for applying selected #ifdef, indeterminate preprocessor logic in place.

### 採用の歴史

The project has a small distribution footprint, with the official page linking both a release tarball and the SourceHut repository.

### 使われ方

Users run cppp with macro symbols defined or undefined on the command line. The tool removes or simplifies conditional-inclusion blocks only when those symbols determine the result.

### パッケージ好きにとっての重要性

cppp is package-nerd interesting because it fills a narrow gap between doing no preprocessing and running the full C preprocessor, preserving source shape while pruning known feature branches.

### タイムライン

- Current release page: The official homepage links cppp-2.9.tar.gz.
- Current source hosting: The official homepage links the SourceHut repository.

### Related projects

- cppp is related to the C preprocessor, but it intentionally performs only partial conditional evaluation instead of full macro preprocessing.
