I am hoping we could give this project a kick-start. I've chosen it to help work with Usenet.com and their posting & propagation problems. Other yencode projects are either closed-source or designed for GUI use (or not very friendly with MacOSX or other *ixen).
I've explained why the patch is needed inside the Patch Tracker record there.
The only part of that patch that can't be done properly is to rename 'ypost' to 'yencee' as it exists in the CVS here. The 'ypost' name conflicts with another Sourceforge project.
So I'm hoping my post here would get noticed and then could we can make a final official tarball of it, please?
Sorry about the very late response. I agree with your your suggested changes and have included them in release 0.16.
