-This package is quite young, so the API may well change as I and

 The API supports access to 'named' kstat statistics, IO statistics,
 and the most common and useful sorts of 'raw' kstat statistics

+IMPORTANT NOTE (March 2020): We no longer use any Solaris or Illumos
+based systems. This package worked fine for us while we had such systems
+and I never found any bugs, but without Illumos systems I'm no longer
+in a position to further update the package in any meaningful way. I
+would be happy to pass this package to someone is still using Solaris
+or Illumos based systems and so can actively develop it, if any further
+development is necessary. I am happy to accept pull requests from people
+with Illumos systems who can do the necessary testing and so on.
+
+Given this, I don't currently expect to release an official version 1.0
+of the package or update it to be a Go module. I would again be happy to
+accept pull requests.
