# snap_cmp   (Snapshot and Compare)

# Usage:   snap_cmp CPLBUG
#
# By: Angel Corbera (corbera@rocketmail.com)
#
# Purpose:   To know which blocks have changed
# their output/status after a CP has been rebooted,
# probably during an On-line upgrade.
# The script will check first if CP is not rebooting.
#
# Procedure:
# Run this script just BEFORE the CP is rebooted.
# It will save current values/status of selected
# blocks (PID controllers, AOUT, etc).
#
# Run this script AGAIN after the CP has rebooted
# completely.
# After getting the new values, the script will
# show ONLY the blocks that have changed their
# output values (AOUT), or Status (M/A, L/R).
#
# MA/LR retrieved from: PID, PIDA, PIDE, PIDX, PIDXE
#                       RATIO
# OUT values retrieved from: AOUT, AOUTR
