This article is from the Apple II GNO FAQ, by Devin Reade with numerous contributions by others.
A#11.6: The GNO libraries are still undergoing active development. If you
find that a standard or common routine is missing, then contact
Devin Reade <gdr@eddore.myrias.com> who is currently the primary
maintainer of the GNO libc.
If the function is not yet in libc you are requested to contribute
an implementation and a man page, preferably in nroff(1) source
(see Q#3.5). Distributing the work results in faster updates.
