-mutt-notmuch - notmuch (of a) helper for Mutt
-
-=head1 SYNOPSIS
-

-=head1 DESCRIPTION
-
-mutt-notmuch 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/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
-
-mutt-notmuch can be used to integrate notmuch with the Mutt mail user agent
-(unsurprisingly, given the name). To that end, you should define the following
-macros in your F<~/.muttrc> (replacing F<~/bin/mutt-notmuch> for the actual
-location of mutt-notmuch on your system):
-
- macro index <F8> \
- "<enter-command>unset wait_key<enter><shell-escape>~/bin/mutt-notmuch --prompt search<enter><change-folder-readonly>~/.cache/mutt_results<enter>" \
- "search mail (using notmuch)"
- macro index <F9> \
- "<enter-command>unset wait_key<enter><pipe-message>~/bin/mutt-notmuch thread<enter><change-folder-readonly>~/.cache/mutt_results<enter><enter-command>set wait_key<enter>" \
- "search and reconstruct owning thread (using notmuch)"
-
-The first macro (activated by <F8>) will prompt the user for notmuch search
-terms and then jump to a temporary maildir showing search results. The second
-macro (activated by <F9>) will reconstruct the thread corresponding to the
-current mail and show it as search results.
-
-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.
