## 项目历史与用法

um is a command-line utility for creating and maintaining personal man-like help pages.

### 项目历史

The project grew out of the observation that traditional man pages are comprehensive but often too long for recurring personal reference. Its README frames um pages as concise Markdown notes that can be rendered into man-like output, with Kramdown replacing an earlier Pandoc-based conversion path.

### 采用历史

The official README documents availability through Homebrew on macOS and Linux, plus Arch Linux AUR packages. The repository's 1.0.0 tag dates to late 2015, giving the tool a long-running but deliberately small CLI footprint.

### 使用方式

Users run commands such as um edit grep, um grep, um list, um rm, and um topic to maintain small per-topic references for commands, CSS properties, or other repeated lookup material.

### 为什么软件包爱好者会关心

um is a package-nerd tool in the literal sense: it helps terminal users write their own compact documentation for commands they repeatedly forget, and it ships through Homebrew/AUR channels rather than a large hosted service.

### 时间线

- 2015: Official repository tag 1.0.0 is associated with a December 2015 commit.
- README era: Project documents the switch from Pandoc to Kramdown for Markdown-to-man-page rendering.
- README era: Official installation lists Homebrew and Arch AUR packages.

### Related projects

- um is related to Unix man pages, roff-style documentation, Markdown note systems, Kramdown, and the broader CLI personal-knowledge workflow.
