"""iView CGI script

This is a script that you can place within your cgi-bin directory to allow
you to download iView videos via HTTP. This is a fairly useless feature
by itself, but very handy if you are trying to integrate iView with a
system that needs to or prefers to download via HTTP.

Usage:
    - place script in /usr/lib/cgi-bin or wherever your cgi-bin is
    - request a video via HTTP:
        $ wget http://localhost/cgi-bin/iview.cgi/730report_10_01_01.flv
    - enjoy!

Note: if there is one thing going to go wrong with this script, it will be
that it can't find the iview include module. Make sure that either the
iview module is installed to the system (preferred), or the iview/
directory is also under cgi-bin.

Also, if there's the slightest chance somebody will be able to access this
script from a public address, it's probably a good idea to configure
your web server to restrict access to this script by IP address. Unless,
of course, you want your web server acting as an iView proxy, chewing up
bandwidth, violating copyright, getting your server taken down, etc.
