Download library for files and recursive websites

 GNU Wget is a network utility to retrieve files from the web
 using HTTP(S) and FTP, the two most widely used internet
 protocols. It works non-interactively, so it will work in
 the background, after having logged off. The program supports
 recursive retrieval of web-authoring pages as well as FTP
 sites -- you can use Wget to make mirrors of archives and
 home pages or to travel the web like a WWW robot.
 .
 This is the library that provides the basic functions needed by
 a webclient.
