some file problems

[NCHU611A]

I've been hosting my own server using your "webcall" program for months.
Then I think this program is very powerful.
So I want to understand the architecture of "webcall".

When I was learning about this program, I didn't know what the two files "gobuild" and "wcadmin" were for.

Would you please tell me what these files are used for?

And then what are those "httpActions.go", "httpAdmin.go"... and other files with the extension ".go" used for?

Thank you !!
