+WireGuard is a VPN that uses state-of-the-art cryptography. It is
+designed as a general purpose VPN for running on embedded interfaces
+and super computers alike, fit for many different circumstances.
+
+WireGuard is not yet complete. You should not rely on this code. It has
+not undergone proper degrees of security auditing and the protocol is
+still subject to change.

+# 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.
