Welcome to ~mu~!

*Note*: you are looking at the *development* branch, which is where new code is
being developed and tested, and which may occasionally break.

Distribution and non-adventurous users are instead recommended to use the [[https://github.com/djcb/mu/tree/release/1.6.x][1.6.x
Release Branch]] or to pick up one of the [[https://github.com/djcb/mu/releases][1.6.x Releases]].

Given the enormous amounts of e-mail many people gather and the importance of
e-mail message in our work-flows, it's essential to quickly deal with all that
mail - in particular, to instantly find that one important e-mail you need right
now, and quickly file away message for later use.

~mu~ is a tool for dealing with e-mail messages stored in the Maildir-format. ~mu~'s
purpose in life is to help you to quickly find the messages you need; in
addition, it allows you to view messages, extract attachments, create new
maildirs, and so on. See the [[www/cheatsheet.md][mu cheatsheet]] for some examples. =mu= is fully
documented.

After indexing your messages into a [[http://www.xapian.org][Xapian]]-database, you can search them using a
custom query language. You can use various message fields or words in the body
text to find the right messages.

Built on top of ~mu~ are some extensions (included in this package):

- mu4e: a full-featured e-mail client that runs inside emacs

- mu-guile: bindings for the Guile/Scheme programming language (version 3.0 and
  later)

~mu~ is written in C and C++; ~mu4e~ is written in ~elisp, and ~mu-guile~ in a mix of
C++ and Scheme.

Note, ~mu~ is available in Linux distributions (e.g. Debian/Ubuntu and Fedora)
under the name ~maildir-utils~; apparently because they don't like short names.
