# This script tries to get good estimations into the .calc files at
# boot/$CODENAME/boot-$ARCH.calc, so you can use it whenever you want to
# update these .calc files with more recent estimations.

# It uses info taken from the temporary dir of a previous build for $ARCH,
# $CODENAME. This doesn't need to be a full build, you can get the needed
# stuff by running a build.sh with something like:
# IMAGETARGET="ok bootable upgrade bin-infos bin-list"

# Temporary directory of the previous build.
BDIR="$TDIR/$CODENAME-$ARCH"

#Get info from older build if it exists
