It took me a while but is Ncat the same thing as netcat?

Edit: ah, clarified by other page:

> Ncat is our modern reinvention of the venerable Netcat (nc) tool released by Hobbit in 1996. While Ncat is similar to Netcat in spirit, they don't share any source code.

There are actually several tools in this vein. Although there are a handful that do, some others don't even go by the name "cat" at all.
