no function to convert .emacs-custom.el into plain emacs lisp

[jidanni]

I have had enough of the "custom facility" and other "helpers stuff"
adding things to the "custom file".

I want to regain control of the s*ituation.

So how can I convert all the stuff that has accrued in

http://jidanni.org/comp/configuration/.emacs-custom.el

into plain .emacs lisp so I can put it into my .emacs file?

Even though I will surely have to do it often, but at least it will be
safe in .emacs, as to this day no program has tried to write to that.
