is there a 'mono-descargar' library in Tampermonkey?

[yuanlin-yu]

I had downloaded a user script lately, and when I am looking into the code from the script, it contains var mono = window['mono-descargar'];. What I want to ask is that if the whole 'mono-descargar' thing is a library or something provided by Tampermonkey?
Because when I use this var mono = window['mono-descargar']; in a new blank chrome extension script, it turn out to be undefined. :D.

No. Seems to be something site specific.
