+#!/bin/bash
+#
+# QEMU network interface configuration script. This utility needs to
+# be run as root, and will use the tunctl binary from a native sysroot.
+# Note: many Linux distros these days still use an older version of
+# tunctl which does not support the group permissions option, hence
+# the need to use build system's version.
+#
+# If you find yourself calling this script a lot, you can add the
+# the following to your /etc/sudoers file to be able to run this
+# command without entering your password each time:
+#
+# <my-username> ALL=NOPASSWD: /path/to/runqemu-ifup
+# <my-username> ALL=NOPASSWD: /path/to/runqemu-ifdown
+#
+# If you'd like to create a bank of tap devices at once, you should use
+# the runqemu-gen-tapdevs script instead. If tap devices are set up using
+# that script, the runqemu script will never end up calling this
+# script.
