-This directory contains a vim script that allows reading notmuch mail
-through vim.
-
-NOTE: this is a work in progress.  Patches welcome. <bart@jukie.net>
-
-Dependencies:
-    notmuch:
-        Naturally, it expects you have notmuch installed and configured.
-
-    sendmail:
-        To send mail, notmuch.vim uses sendmail as default.  Most modern MTAs
-        provide a compatibility binary, and so should work well.
-
-
-To install:
-        make install
-
-
-To run:
-        vim -c ':NotMuch'
-
-    from vim:
-        :NotMuch
-        :NotMuch new to:bart@jukie.net 'subject:this is a test'
-
-
-Buffer types:
-    [notmuch-folders]
-        Folder list, or technically a list of saved searches.
-
-        Keybindings:
-            <Enter> - show the selected search
-            m       - compose a new message
-            s       - enter search criteria
-            =       - refresh display
-
-    [notmuch-search]
-        You are presented with the search results when you run :NotMuch.
-
-        Keybindings:
-            <Space> - show the selected thread collapsing unmatched items
-            <Enter> - show the entire selected thread
-            a       - archive message (remove inbox tag)
-            f       - filter the current search terms
-            o       - toggle search screen order
-            m       - compose a new message
-            r       - reply to thread
-            s       - enter search criteria
-            ,s      - alter search criteria
-            t       - filter the current search terms with tags
-            q       - return to folder display, or undo filter
-            +       - add tag(s) to selected message
-            -       - remove tag(s) from selected message
-            =       - refresh display
-            ?       - reveal the thread ID of what's under cursor
-            ^]      - search using word under cursor
-
-    [notmuch-show]
-        This is the display of the message.
-
-        Keybindings:
-            <Space> - mark read, archive, go to next matching message
-            ^n      - next message
-            ^p      - previous message
-            b       - toggle folding of message bodies
-            c       - toggle folding of citations
-            h       - toggle folding of extra header lines
-            i       - toggle folding of signatures
-            m       - compose a new message
-            r       - reply to the message
-            s       - enter search criteria
-            q       - return to search display
-            ?       - reveal the message and thread IDs of what's under cursor
-            ^]      - search using word under cursor
-
-    [notmuch-compose]
-        When you're writing an email, you're in this mode.
-
-        Insert-mode keybindings:
-            <Tab>   - go to the next header line
-
-        Normal-mode keybindings:
-            <Tab>   - go to the next header line
-            ,s      - send this message
-            ,q      - abort this message
