TinTin++ Homepage
The TinTin++ Homepage has more information available, a manual, example scripts, and a page to help you install/compile it. The download section holds the source code, a compiled binary for linux, and a binary for OS X 10.2, for most linux systems the binary is all you need to run TinTin++, no other files are require.
What is TinTin++?
TinTin++ is a client program specialized to help in playing MUDs. It runs on all unix based systems, this includes MAC OS X 10.2.
What's New?
Some new functionality was added, and the scripting engine has been pretty much completely rewritten. In reality, more than 50% of the program has been rewritten. The end goal was to create a clean, straightforward, fast and easy (but powerful) mud client. TinTin++ 1.90 more than accomplishes that goal.
But I run Windows ... now what??
Use a special port called WinTin++
