dropped the support for Python 2.5

let's elaborate the decision: Python 2.5 is a 6 years old release
and "under the current release policy, no security issues in Python
2.5 will be fixed anymore" (!!); also, it doesn't support the new
zipfile distribution format.

 ## DESCRIPTION
 **youtube-dl** is a small command-line program to download videos from
 YouTube.com and a few more sites. It requires the Python interpreter, version
-2.x (x being at least 5), and it is not platform specific. It should work in
+2.x (x being at least 6), and it is not platform specific. It should work in
 your Unix box, in Windows or in Mac OS X. It is released to the public domain,
 which means you can modify it, redistribute it or use it however you like.
