# The original ("yes") patch allows user apps to gain the ability to spoof
# themselves as other apps, which can be a major security threat. Using the
# restricted patch and embedding the apps that requires it as system privileged
# apps is a much secure option. See the README.md ("Custom mode") for an
# example.
#
