* Welcome to mu! 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. [[http://www.djcbsoftware.nl/code/mu][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 [[http://www.djcbsoftware.nl/code/mu/cheatsheet.html][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): - mu-for-emacs ([[http://www.djcbsoftware.nl/code/mu/mu4e.html][mu4e]]): a full-featured e-mail client that runs inside emacs - [[http://www.djcbsoftware.nl/code/mu/mu-guile.html][mu-guile]]: bindings for the Guile/Scheme programming language (version 2.0 and later) - a toy GTK+-interface called 'mug' (in the 'toys/' subdir) =mu= is written in C and a bit of C++ (to interface with Xapian), with =mu4e= written in [[http://en.wikipedia.org/wiki/Emacs-Lisp][Emacs-Lisp]] and =mu-guile= in a mix of C and Scheme. Note, =mu= is available in Debian/Ubuntu under the name =maildir-utils=; apparently because they don't like short names. It's also possible to confuse that name with the [[http://mailutils.org/][GNU Mailutils]] project (which is totally unrelated) - but now you have been warned. You can install `mu` package in the openSUSE Linux distro with `zypper in maildir-utils`
