The Dink Network

What are the best ways to tell what versions of dink executable we are running? You can always use the Help/About menu pull-down on Dfarc to get version information. What is the best way to identify the version of dink or freedink or dink.exe or freedink.exe?

I think I know what to do for freedink on ubuntu.

x@y:~$ apt-cache policy freedink
freedink:
  Installed: 108.4-1
  Candidate: 108.4-1
  Version table:
 *** 108.4-1 500
