+notmuch-mutt: Notmuch (of a) helper for Mutt
+============================================
+
+notmuch-mutt provide integration among the [Mutt] [1] mail user agent and the
+[Notmuch] [2] mail indexer.
+
+notmuch-mutt offer two main integration features. The first one is the ability
+of stating a **search query interactively** and then jump to a fresh Maildir
+containing its search results only. The second one is the ability to
+**reconstruct threads on the fly** starting from the currently highlighted
+mail, which comes handy when a thread has been split across different maildirs,
+archived, or the like.
+
+notmuch-mutt enables to trigger mail searches via a Mutt macro (usually F8) and
+reconstruct threads via another (usually F9). Check the manpage for the 2-liner
+configuration snippet for your Mutt configuration files (~/.muttrc,
+/etc/Muttrc, or a /etc/Muttrc.d snippet).
+
+A [blog style introduction] [3] to notmuch-mutt is available and includes some
+more rationale for its existence.
+
+Arguably, some of the logics of notmuch-mutt could disappear by adding support
+for a --output=symlinks flag to notmuch.

+
+Requirements
+------------
+
+To *run* notmuch-mutt you will need Perl with the following libraries:
+
+- Mail::Box <http://search.cpan.org/~markov/Mail-Box/>
+ (Debian package: libmail-box-perl)
+- Mail::Internet <http://search.cpan.org/~markov/MailTools/>
+ (Debian package: libmailtools-perl)
+- String::ShellQuote <http://search.cpan.org/~rosch/String-ShellQuote/ShellQuote.pm>
+ (Debian package: libstring-shellquote-perl)
+- Term::ReadLine <http://search.cpan.org/~hayashi/Term-ReadLine-Gnu/>
+ (Debian package: libterm-readline-gnu-perl)
+
+To *build* notmuch-mutt documentation you will need:
+
+- pod2man (coming with Perl) to generate the manpage
+- markdown to generate README.html out of this file

+
+notmuch-mutt - notmuch (of a) helper for Mutt
+
+=head1 SYNOPSIS
+
+=over
+
+=item B<notmuch-mutt> [I<OPTION>]... search [I<SEARCH-TERM>]...
+
+=item B<notmuch-mutt> [I<OPTION>]... thread < I<MAIL>
+

+
+=head1 DESCRIPTION
+
+notmuch-mutt is a frontend to the notmuch mail indexer capable of populating
+maildir with search results.
+
+=head1 OPTIONS
+
+=over 4
+
+=item -o DIR
+
+=item --output-dir DIR
+
+Store search results as (symlink) messages under maildir DIR. Beware: DIR will
+be overwritten. (Default: F<~/.cache/notmuch/mutt/results/>)
+
+=item -p
+
+=item --prompt
+
+Instead of using command line search terms, prompt the user for them (only for
+"search").
+
+=item -h
+
+=item --help
+
+Show usage information and exit.
+
+=back
+
+=head1 INTEGRATION WITH MUTT
+
+notmuch-mutt can be used to integrate notmuch with the Mutt mail user agent
+(unsurprisingly, given the name). To that end, you should define macros like
+the following in your Mutt configuration (usually one of: F<~/.muttrc>,
+F</etc/Muttrc>, or a configuration snippet under F</etc/Muttrc.d/>):
+
+ macro index <F8> \
+ "<enter-command>unset wait_key<enter><shell-escape>notmuch-mutt --prompt search<enter><change-folder-readonly>~/.cache/notmuch/mutt/results<enter>" \
+ "notmuch: search mail"
+ macro index <F9> \
+ "<enter-command>unset wait_key<enter><pipe-message>notmuch-mutt thread<enter><change-folder-readonly>~/.cache/notmuch/mutt/results<enter><enter-command>set wait_key<enter>" \
+ "notmuch: reconstruct thread"
+ macro index <F6> \
+ "<enter-command>unset wait_key<enter><pipe-message>notmuch-mutt tag -inbox<enter>" \
+ "notmuch: remove message from inbox"
+
+The first macro (activated by <F8>) prompts the user for notmuch search terms
+and then jump to a temporary maildir showing search results. The second macro
+(activated by <F9>) reconstructs the thread corresponding to the current mail
+and show it as search results. The third macro (activated by <F6>) removes the
+tag C<inbox> from the current message; by changing C<-inbox> this macro may be
+customised to add or remove tags appropriate to the users notmuch work-flow.
+
+To keep notmuch index current you should then periodically run C<notmuch
+new>. Depending on your local mail setup, you might want to do that via cron,
+as a hook triggered by mail retrieval, etc.
