Can anyone identify this javascript forum script name?

[Simon.h]

Hi there all,

I was asked to install and embed into html page a threaded forum made of JS.
I saw it in three places already.

Can you please look at the implementation here and tell me what script is it?

I think that copy of some source files of the script is located here:

Do you know, please?

Thank you in advance,

Simon
