-- turbonss has not been fuzz-tested, so it will crash a program on invalid

-- if the database file was replaced while the program has been running,

+Turbonss works, but, to the author's knowledge, was not deployed to production.
+If you want to use turbonss instead of a battle-tested, albeit slower nscd,
+keep the following in mind:
+- turbonss has not been fuzz-tested, so it will crash a program on invalid
+  database file. Please compile with `ReleaseSafe`. It is plenty fast with this
+  mode, but an invalid database will lead to defined behavior (i.e. crash with
+  a stack trace) instead of overwriting memory wherever.
+- if the database file was replaced while the program has been running,
+  turbonss will not re-read the file (it holds to the previous file
+  descriptor).
+- requires a nightly version of zig (that will change with 0.11).
+
+The license is permissive, so feel free to fork and implement the above (I
+would appreciate if you told me, but surely you don't have to). I am also
+available for [consulting][consulting] if that's your preference instead.
