[Perl] Script to check stock

Script to check the stock and their graph :D
Uses finance.yahoo.com to get the graphs.

INPUT : stock.conf : contains stock symbol (one per line ) for each company.
You can find the symbols on http://finance.yahoo.com/lookup, if you don't know.

OUTPUT: Generates a html page that contains the information and graph for the given companies in stock.conf.

Requires: lynx
Usages: Put stocks.cgi and stock.conf in your cgi-bin directory. Open in firefox. Refresh to get latest info.
Note: you can also run the script from shell prompt and then redirect the output to a html file , then open this file in firefox :D But you need to run it every time you want the latest info.

The Fastest Language

Well,
Though this post is a little digression from what this forum is meant
for. It is really an interesting one because many a times we think

Which language is the fastest?

Considering the same hardware/environments are provided, it will all
depend on how well a compiler/interpreter make use of underlying
hardware/environment to generate native/interpreted code.

In a computer language shootout [Survey]
differrent compiler for different languages tested against their
ability to translate code for Ackermann Function
[Ackermann_function], Fibonacci numbers[Fibonacci_number] and
Tak functions [TAKFunction.html].

I was really happy to see that my favourite compiler gcc rules :-)
