+
+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.
