what is plink? putty?

[thufir]

I was looking at driving telnet, and came across putty and plink.  Putty 
has a good Wikipedia entry, but only says this about plink:

Plink: a command-line interface to the PuTTY back ends



a quick search through apt-cache shows:

http://packages.ubuntu.com/wily/libjsch-agent-proxy-java

which looks interesting.  While there are numerous telnet libraries, I'd 
rather use the system telnet. Thoughts or pointers?



thanks,

Thufir
