# Either bash or ksh will be ok for this; requires 'test -ot'

#  (-p above just says to not parse $ENV file; makes it faster for

#   those of us who set $ENV)

#

# Update RTEMS applications for the API changes from 3.1.0 to 3.2.0

#

# NOTE

#

#   This is potentially a very dangerous program.

progname=${0##*/}        # fast basename hack for ksh, bash

USAGE=\

"

usage: $progname [ -vs ] [ -b base_directory ] [-p file] [-f] [files...]

        -v          -- verbose

        -p          -- file with replacement instructions

        -s          -- skip prompt for backup verification

        -f          -- do files at end of line

base_directory is the root directory of the source code to update.  It

defaults to the current directory.

This program updates C, H, and .inl files.
