# To add new entries to the bugtool, you need to:
#
# Create a new capability. These declare the new entry to the GUI, including
# the expected size, time to collect, privacy implications, and whether the
# capability should be selected by default. One capability may refer to
# multiple files, assuming that they can be reasonably grouped together, and
# have the same privacy implications. You need:
#
# A new CAP_ constant.
# A cap() invocation to declare the capability.
#
# You then need to add calls to main() to collect the files. These will
# typically be calls to the helpers file_output(), tree_output(), cmd_output(),
# or func_output().
#
# Special pylint disables for latest pylint on xen-bugtool itself (for the moment):
# The old Pylint-1.9.x thinks some of these are useless:
# pylint: disable=useless-suppression

# pylint: disable=broad-exception-raised,missing-type-doc,useless-object-inheritance

This application will collate the Xen dmesg output, details of the
hardware configuration of your machine, information about the build of
Xen that you are using, plus, if you allow it, various logs.
The collated information will be saved as a .%s for archiving or
sending to a Technical Support Representative.
The logs may contain private information, and if you are at all
worried about that, you should exit now, or you should explicitly
exclude those logs from the archive.
