## プロジェクトの歴史と使われ方

sub2srt is a small Perl command-line converter for subtitle files. Its README describes converting common `.sub` subtitle formats, including MicroDVD and SubRip-style inputs, into SubViewer `.srt` output suitable for tools such as ogmmerge.

### プロジェクトの歴史

The README credits Roland Obermayer and describes the tool as a quick hack written after inspecting subtitle file layouts rather than from formal format documentation. Its bundled changelog records an initial 0.5 release on 2003-08-26, followed by small format and encoding updates through 2014.

### 採用の歴史

Its package-manager footprint is narrow: the input package-manager facts list Homebrew, and the README says installation is simply copying the single Perl script into a directory on `PATH`. That single-file script shape is typical of older media-conversion utilities that survived because they solved one awkward conversion job.

### 使われ方

Users run `sub2srt --help` for options and invoke the script to convert supported text subtitle formats. The README explicitly says it does not convert DVD subtitles or VobSub, which keeps the tool scoped to text subtitle conversion rather than OCR or bitmap subtitle workflows.

### パッケージ好きにとっての重要性

sub2srt is package-nerd-interesting less because it is large and more because it is tiny, old, and still packageable: a single Perl script with GPL-2 licensing, no runtime beyond Perl, and a narrow CLI purpose that Homebrew can preserve for users who hit legacy subtitle files.

### タイムライン

- 2003-08-26: Initial sub2srt 0.5 release recorded in the README changelog.
- 2005-01-15: sub2srt 0.5.3 added txtsub input support.
- 2013-11-02: sub2srt 0.5.4 added MPL2 and TMP input format support.
- 2014-12-10: sub2srt 0.5.5 added support for encoding output with piconv.

### Related projects

- The README mentions MicroDVD, SubRip-style `.sub` input, SubViewer `.srt` output, ogmmerge, Perl, and excludes DVD subtitles and VobSub from scope.
