# 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().
