    -p, --profile=NAME
            Load a specific profile on startup.

    -o, --output=FILENAME
            Specify a filename to save the screenshot to (overwrites any
            profile-related setting).

            Supported image formats: You can save to any popular image
            format (e.g. jpeg, png, gif, bmp). Additionally it is possible
            to save to pdf, ps or svg.

            Please note: There are several wildcards available, like

             %Y = year
             %m = month
             %d = day
             %T = time
             $w = width
             $h = height
             $name = multi-purpose (e.g. window title)
             $nb_name = like $name but without blanks in resulting strings
             $profile = name of current profile
             $R = random char (e.g. $RRRR = ag4r)
             %NN = counter

            The string is interpretted by strftime. See "man strftime" for
            more examples.

            As an example: shutter -f -e -o './%y-%m-%d_$w_$h.png' would
            create a file named '11-10-28_1280_800.png' in the current
            directory.

    -d, --delay=SECONDS

            using Shutter in scripts.

4. 使ってみる

shutter -s -o /tmp/work/SS/a.png

　scrotではできない範囲指定ができた。ほかにも編集できる（矢印・テキスト・モザイクなど）。SVG出力まであった。

気になったこと

• アプリ固有のアップデートが実行されてウザかった
• 消費メモリが約70MBもある
• 一度起動すると常駐する

所感

　常駐＆重いので使えない。残念。
