# This lists all the available crash annotations.
#
# Mandatory fields for each entry are:
# - description: A string describing the annotation
# - type: the annotation type, currently `string`, `integer` or `boolean`.
#   The latter are stringified to `1` for true and `0` for false.
#
# Additionally a field can have the following optional fields:
# - altname: A string that will be used when writing out the annotation to the
#   .extra file instead of the annotation name
# - ping: A boolean that indicates whether the annotation is whitelisted for
#   going into the crash ping, if not specified this defaults to false
