Disables allowing the python argparse library from automatically shortening command line arguments, this prevents issues whereby a new command is added and code that wrongly uses the shortened command of an existing argument which is the same as the new command being added will silently change script behaviour.

# A script to diff between two ram or rom reports generated by
|
|
# size_report. When you call call the ram_report or rom_report targets you
|
|
# end up with a json file in the build directory that can be used as input
|
|
# for this script.
|
|
|
|
# The output shows which symbols increased and which decreased in size and
|
|
# also tracked added/remove symbols as well.
|
|
|
|
# Example:
|
|
# ./scripts/footprint/fpdiff.py ram1.json ram2.json
