#
# Before calling any functions, requires that the following
# have already been defined/sourced in the calling script:
#
# SCALING - Number of times an individual file will be processed
# FILECOUNT - Number of files that will have operations performed on them
#
# For example, most updates set SCALING=3 because a patched file is
# processed like so: (patch to tmp, copy to root file system, verify
# version on root filesystem). Scaling can change depending on options
# passed during update generation.
#
# Alternatively, if you know the exact number of times that you'll be
# calling "update_percent_complete_scaled 1", the values could be set
# like so:
#
# SCALING=1
# FILECOUNT=NO_OF_UPDATE_CALLS
#
#
# Also requires that the following have been sourced:
# * "gui abstraction" - blanket or eips
#
# NOTE: There's no cleanup of PROG_COMPLETE since this is solely tmpfs
# on device and is expected to be rebooted immediately after execution.
