## 项目历史与用法

GNU cppi is a small GNU developer tool for indenting C preprocessor directives so their nesting is visible.

### 项目历史

The package is maintained as a GNU program, with Savannah hosting its project and source repository and GNU publishing the user manual and release tarballs.

### 采用历史

Its adoption is typical of compact GNU command-line utilities: it appears in Unix package collections as a formatting and lint-adjacent aid for C and C++ source trees.

### 使用方式

cppi is used from the command line on source files to make conditional-preprocessor structure easier to review by aligning directives with their nesting level.

### 为什么软件包爱好者会关心

The package matters to maintainers because it is narrowly scoped, reproducibly distributed through GNU release archives, and useful in style or cleanup pipelines without pulling in a full C formatter.

### 时间线

- 2010: GNU FTP archive lists cppi 1.14 and 1.15 release tarballs.
- 2013: GNU FTP archive lists cppi 1.18 release tarballs.

### Related projects

- cppi sits near C formatting and linting tools, but its official scope is specifically C preprocessor directive indentation.
