The library is only being developed and may be noticeably changed in the future. It was completely written and is maintained by me.
In order to demonstrate the abilities of the library, I decided to create the DjVu.js Viewer. The main idea is to create a plug-in that can be easily included to any web page. DjVu Viewer now is very simple and can't do much, but I hope to improve it a lot in the future.
If you have a djvu document that can't be rendered by the DjVu.js Viewer, please send it to me. It's very important, since the djvu format is quite complicated and I didn't tested all code of my library, since I just don't have appropriate examples of djvu files.
And, of course, any contribution is welcome :)
