The description of the abby package says:
"front-end for cclive and clive abby is a front-end for cclive and clive used to download videos from Youtube and other similar video hosts. Abby is written in C++ and depends on the Qt framework."
Also, the website of the project says:
"abby is a front-end (or a graphical user interface) for cclive and clive that can be used to download videos from Youtube and similar video hosting services. See the above links for a more complete list of supported video websites."
But when trying to add a link of a video in youtube, the program pops up an error message saying:
"www.youtube.com: unsupported website"
What is the matter? If it does not support Youtube, why use a misleading information in the program description?
