# This is a simple helper script for smtp-notify which looks for certain
# expansion macros, which we've committed and converts them to valid
# libfmd_msg macros which directly reference event payload members.
#
# This allows us to change event payload names or alter the libfmd_msg
# expansion macro syntax without breaking user-supplied message body
# templates.
#
# We use all-caps for the committed macro names to avoid colliding
# with an actual event payload member name.
#
# Usage: process_msg_template.sh <infile> <outfile> <code> <severity>
#

# Verify template exists, is readable and is an ascii text file
