3     # This script is based on work of mendel from
4     # http://www.lafferty.ca/software/webshots/webshot
5     # webshot: hackish thing to take a picture of a whole webpage.
6     #
7     # idea from sippey (http://www.sippey.com/2004/blog-snaps/)
8     # inspiration from bradfitz
9     #
10     # usage: webshot url filename
11     #
12     # JPEG seems to be the best format.
13     #
14     # Modified by Dobrica Pavlinusic 2004-07-25
15     # - include signal grabbing
16     # - dynamic vncserver display
17     # - correct WindowID parsing
18     # - wait for browser to load full page (useful on slow links)
19     #
20     # It will need follwing external utilities:
21     # vncserver
22     # mozilla-firefox
23     # HEAD (part or LWP perl library, it can be commented out)
24     # nc (netcat, to simulate web server)
25     # xwininfo (standard part of X-clients)
26     # xwit (not so standard command, but very useful)
27     # import (part of ImageMagick package)
28     #
29     # It will create snapshot of following size
30     W=800
31     H=800
