## プロジェクトの歴史と使われ方

mu is Dirk-Jan C. Binnema's Maildir search and indexing toolkit for Unix-like systems. The project site says the first mu versions date to 2008, and presents the package as a response to large personal mail stores: index the Maildir once, then find, view, extract attachments from, and organize messages through command-line tools.

### プロジェクトの歴史

Its technical niche is the combination of fast Maildir indexing, a Xapian-backed query database, and package-shipped companion interfaces. The best-known companion is mu4e, a GNU Emacs mail client built on top of mu; the package also exposes Guile/Scheme bindings. In practice, users initialize a database for a Maildir, run `mu index` after mail is delivered by tools such as mbsync, offlineimap, or fetchmail, and query it from the `mu` CLI or from mu4e inside Emacs.

### 使われ方

In package-manager terms, mu sits at the intersection of mail tooling, desktop productivity, and Emacs workflows. It is packaged by several Unix-like distributions, sometimes under the name `maildir-utils`, while Homebrew and similar managers expose it as `mu`.
