+Tini is a tiny but valid init for containers.  All Tini does is spawn a
+single child (Tini is meant to be run in a container), and wait for it
+to exit all the while reaping zombies and performing signal forwarding.
+
+Using Tini has several benefits:
+
+- It protects you from software that accidentally creates zombie
+  processes, which can (over time!) starve your entire system for PIDs
+  (and make it unusable).
+- It ensures that the default signal handlers work for the software you
+  run in your Docker image.  For example, with Tini, SIGTERM properly
+  terminates your process even if you didn't explicitly install a signal
+  handler for it.
+- It does so completely transparently!  Docker images that work without
+  Tini will work with Tini without any changes.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
