## プロジェクトの歴史と使われ方

git-cal is a small Perl command-line tool that renders a GitHub-style contributions calendar from local Git history.

### プロジェクトの歴史

The project is distributed from Karthik Katooru's GitHub repository and packaged as a single executable Perl script. The repository exposes v0.9 and v0.9.1 releases, with v0.9.1 described as a no-external-dependencies release.

### 採用の歴史

Adoption evidence is modest: the official README documents Homebrew installation, and the repository shows a niche but visible audience for a terminal contribution-calendar tool. That points to a utility used by command-line Git users rather than a broad ecosystem platform.

### 使われ方

Practitioners run git-cal inside or against a repository to inspect commit activity over roughly a year. Options support ANSI color, ASCII, Unicode output, author filtering, all-branch history, period selection, and path-limited history.

### パッケージ好きにとっての重要性

For package catalogs, git-cal is notable mostly as a tiny Unix-style Git companion: one executable Perl script, no CPAN dependencies declared in Makefile.PL, and behavior driven by Git log output.

### タイムライン

- 2013: v0.9-era releases published in the official GitHub repository.
- 2013: v0.9.1 listed as the latest release with no external dependencies.
- 2010s: Homebrew installation documented in the official README.

### Related projects

- git-cal relates to contribution graphs in hosted Git forges, especially GitHub's contribution calendar, and to other terminal Git summary tools.
