nwrite - 1.9.2-20.1+b1 main

Nwrite is a replacement for the standard write program that lets you write
directly to the terminal of another logged-in user without the overhead of talk
taking over the full screen or the other user having to respond first.
.
Nwrite's advantages over traditional write include the ability to send the same
message simultaneously to multiple users, and a receiver-configurable message
format, including a tag at the start of each line that identifies the sender.
