# vim:syntax=apparmor

# This abstraction is designed to be used in a child profile to limit what
# confined application can invoke via kde-open5 helper.
#
# NOTE: most likely you want to use xdg-open abstraction instead for better
# portability across desktop environments, unless you are sure that confined
# application only uses /usr/bin/kde-open5 directly.
#
# Usage example:
#
# ```
# profile foo /usr/bin/foo {
# ...
# /usr/bin/kde-open5 rPx -> foo//kde-open5,
# ...
# } # end of main profile
#
# # out-of-line child profile
# profile foo//kde-open5 {
#   #include <abstractions/kde-open5>

#   # Only allow to handle http[s]: and mailto: links
#   #include <abstractions/ubuntu-browsers>

#   # Add if accesibility access is considered as required

#   # Add if audio support for message box is
#   # considered as required.
