## プロジェクトの歴史と使われ方
extract_url.pl is a Perl utility that extracts URLs from MIME email messages or plain text, designed especially for use with the mutt email client and as a replacement or pre-parser for urlview.
### プロジェクトの歴史
The official homepage documents version 1.6.1 and says the source repository moved from Google Code to GitHub. The GitHub repository description records it as automatically exported from code.google.com/p/extracturl.
### 採用の歴史
The supplied package metadata lists Homebrew and Nix packages. The official homepage also notes packaging-oriented changes such as a distribution-friendly package layout in the 1.5.7 release history.
### 使われ方
The homepage documents piping email through extract_url.pl, using it with urlview, invoking it on message files, and configuring mutt macros. It also documents options for help, man output, list mode, plain-text mode, quoted-printable decoding, config file selection, and version output.
### パッケージ好きにとっての重要性
extract_url.pl is a classic small Unix email helper: it composes through pipes, integrates with mutt, has a dotfile configuration path, and fills gaps in older URL selectors around MIME, quoted-printable, duplicate URLs, and shell-safe URL handling.
### タイムライン
- 2008: Official NEWS records 1.3.x and 1.4 releases.
- 2009: Official NEWS records 1.5 release.
- 2013: Official NEWS records distribution-friendly packaging work in 1.5.7.
- 2015: GitHub repository was created from the former Google Code project.
- 2017: Official NEWS records 1.6.2 with dependency-location fixes and ALTSELECT default change.
### Related projects
- The official homepage compares extract_url.pl with urlview and urlscan.
- The documented workflow is primarily tied to mutt, while optional Perl modules such as URI::Find and Curses::UI broaden URL detection and interface behavior.
