I don't know of it either.  Frank Harrell's references for binconf are

     A. Agresti and B.A. Coull, Approximate is better than "exact" for
     interval estimation of binomial proportions,   American
     Statistician, 52:119-126, 1998.

     transformation, American Statistician, 55:200-202, 2001.

and there is another paper by the last set of authors
