Include only local subsections into TOC. This prevent duplication of
TOC when build single page HTML document. Also this make unnecessary CSS hack
to hide document title as top level section.

Screenshort movies.
===================
Screenshort movie by mencoder.
------------------------------
::
$ mencoder "mf://*.jpg" -mf fps=30 -o output.avi
Screenshort movie by ffmpeg.
----------------------------
::
mplayer -ao null -ss 0:0:33 -endpos 2 eagles.avi -vo jpeg:outdir=~/dir
mplayer -ao null -ss 0:0:33 -endpos 2 eagles.avi -vo png:z=9:outdir=~/dir
Here:
* ``-ss`` tells mplayer where you begin
* ``-endpos`` tells mplayer where to stop (minutes)
* ``z=9`` sets compression level
ImageMagic and shell script.
----------------------------
::
#!/bin/bash
let iter=1
while [ "$iter" -le "$stop" ]; do
import $iter.png
sleep 1
let x+=1
done
If you interesting in capturing specific window - by 'xwininfo' find,
intereesting your window id (hex value) and use command::
import -window $windowid $iter.png
To quick view result run::
$ cd $img_dir
$ animate -delay 20 *.png
^C
To compound image together::
$ convert -delay 20 *.png capture.mng # license free, multi-image file format
$ convert -delay 20 *.png capture.gif
You can add text to pictures before compound theirs::
$ mogrify -fill yellow -draw 'Rectangle 10,10 150,30' -fill black -pointsize 14 \
-draw 'text 15,25 "by http://example.com"' $iter.png
If screen capturing slow for you use MIFF file format.
Use root flag to capture all screen::
$ import -window root $iter.png
