It is so simple! Look into the file the option *custom-file* points to
(if nil then the file the variable *user-init-file* points to) and you will
see there is nothing else then onw big `custom-set-variables' call.
The only important thing for changing defcustom-options via elisp is not to
use `setq' (or `let') because then all the :set, :initialize (and other)
clauses of the defcustom-form will no be evaluated which can result in
unwanted effects!
But i strongly recommend always using the customize-feature of Emacs for
changing defcustom-options!
BTW, just for my interest: What do you mean with "in context"??
