+Authorization (SPA) for Linux systems running iptables.
+
+This optionally uses gpg and libgpgme if they are available.  Using
+gpg with fwknop is highly recommended.

+# 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.
