Where can we find it?

You can download it from the following link:

http://sourceforge.net/projects/flareget/

There is no source code available in you git repositiory.

The source code is still undocumented. Its no use uploading there yet.

Perhaps, the app might not be open source.

But how can I test you app on windows?

Actually, i have no plans to port it to windows, as lot of downloaders are already available for windows.

Then you should adjust you description, because form Sourceforge:
“flareGet is a full featured multi-threaded and multisegment download manager for Linux, Windows and Mac. It supports browser integration through addons and many more features.”

Oh! I forgot that. I will change that soon.
