# Report events to the metrics collector from non-shell subcommands.
# How to use it:
#   - if the caller subcommand is Bash, don't use this, just source
#     lib/metrics.sh and call track-subcommand-custom-event directly
#   - if the caller subcommand is in any other language, fork a process
#     and execute:
#       bash ${FUCHSIA_DIR}/tools/devshell/lib/metrics_custom_report.sh SUBCOMMAND ACTION [LABEL]
#
#  Custom events will be reported to Google Analytics, if metrics are enabled, as:
#      event category="fx_custom_SUBCOMMAND"
#      event_action="ACTION"
#      event label="LABEL"
#
# This command respects the user's opt-in/out set by fx metrics.
#
# WARNING: This is not supposed to be directly executed by users.
