QNAP/Linux Tool - wget (1) Mirror Websites

GNU Wget was developed to fetch files from the Internet (the Web), in which HTTP, HTTPS, FTP, and many widely used protocols are supported. Since 1996, wget was born for the crawling Web requirement. I firstly studied wget source code in 1998 due to developing crawler programs for search engine.

That is you can not install any software with only one click on setup.exe, the pre-required libraries and packages must manually installed before you can run a powerful App written with Qt for example. In Ubuntu, you are familiar with using apt-get to install packages. In QTS, you must learn how to use ipkg.
