+Subject: [PATCH] test: Implement self-test functionality
+
+This allows to run 'test' unattended by setting environment variable
+SELFTEST=on. Instead of printing the settings libkeepalive should have
+changed, it uses the input values still present in environment to assert
+them being set correctly.

+This will call 'test' three times: The first call makes sure that
+KEEPALIVE=off is respected, the last two calls check that environment
