ABOUT='''\
|
|
calibre is the one stop solution for all your ebook needs. It was created
|
|
originally by Kovid Goyal, to help him manage his ebook collection and is now
|
|
very actively developed by an international community of ebook enthusiasts.
|
|
|
|
Its goal is to empower you, the user, to do whatever you like with the ebooks
|
|
in your collection. You can convert them to many different formats, read them
|
|
on your computer, send them to many different devices, edit their metadata
|
|
and covers, etc.
|
|
|
|
calibre also allows you to download news from a variety of different sources all
|
|
over the Internet and read conveniently in ebooks form. In keeping with its
|
|
philosophy of empowering the user, it has a simple system to allow you to add
|
|
your own favorite news sources. In fact, most the built-in news sources in
|
|
calibre were originally contributed by users.
