GPIO button and userspace

[Alex RAY]

Hackers
help find the correct answer, in what way I can send interrupt on GPIO to
the userspace script.
I know that I can make the device, and open it in program, but it is
cumbersome.
I know what I can run the script from the kernel, as in Linux, but I think
this is not the right way?
