=============================> Specifying A Proxy <=============================
By default proxy information will be read from the environment variables: proxy,
all_proxy and http_proxy, proxy options can also by specified with the -p switch

<type> := "http://" | "socks5://"
<serif> := <username> (":" <password>)? "@"
<proxy> := "None" | <type>? <sering>? <host> (":" <port>)?

Here are some examples (In case you are unfamiliar with the BNF):

http://user:password@myproxyserver:8080
socks5://myproxyserver
None

===============================> Static version <===============================
On the wkhtmltopdf website you can download a static version of wkhtmltopdf 
<http://code.google.com/p/wkhtmltopdf/downloads/list>. This static binary will
work on most systems and comes with a build in patched QT.

Unfortunately the static binary is not particularly static, on Linux it depends
on both glibc and openssl, furthermore you will need to have an xserver
installed but not necessary running. You will need to have different fonts
install including xfonts-scalable (Type1), and msttcorefonts.  See 
<http://code.google.com/p/wkhtmltopdf/wiki/static> for trouble shouting.

================================> Compilation <=================================
It can happen that the static binary does not work for your system for one
reason or the other, in that case you might need to compile wkhtmltoimage
yourself.



================================> Installation <================================
There are several ways to install wkhtmltoimage.  You can download a already
compiled binary, or you can compile wkhtmltoimage yourself. 

==================================> Examples <==================================
This section presents a number of examples of how to invoke wkhtmltoimage.

To convert a remote HTML file to PNG:
