Why they were removed from sources?  Because none is maintaining
it anymore.   As you know Russ has been doing it, but he is a graduate
student at MIT which means he must be very busy for his own Ph.D
thema etc.   Furthermore, maintaining Ghostscript is not any creative
work which is neccessary to those students.   We need Ghostscript for
every day use of Plan 9, and that's all.    Ghostscript is not in the main
stream of Plan 9 design way, it uses UTF-8, but Ghostscript(8.x) uses
CID-keyd character etc.   To maintain Ghostscript is easy enough even
for like me, which don't need Russ, Dave, Jim, Sape, and of course Rob.
I think that's the reason.
