Chrome extension - download files in external download manager (by ctrl + alt + click)

The extension allows you to call a third-party file download manager from chrome. To open a link with an external program, you need to poke ctrl and alt into it.

To work requires an additional program chromeget.py - for Linux and MacOS. In the windows version , chromeget.exe (it takes up 2 megabytes in the archive because it includes python).

The program is a simple single-threaded web server on python, which happens on port 4000 and processes requests only from 127.0.0.1
The request looks like this: 127.0.0.1 : 40000 / http: //link.url/…
Run the program like this: python /path/to/chromeget.py download_manager, where download_manager is your
a download manager, such as uget-gtk, gwget, kget, wget, etc. (in linux, if the parameter is not set, it will try to find any known program)
In windows - c: \ somewhere \ chromeget.exe “c: \ program files \ flashget \ flashget.exe” (this works only with flashget 1.96, in flashget 3.x, as far as I understood, they somehow removed the ability to run from command line)

If you constantly use this thing, it makes sense to put chromeget.py in autorun.

UPD. Well, the expansion itself.
