# ======================== FUNCTIONS =============================
#
# die: logs an error message and exits.
#    A common use for "die" is with a test:
#         test -f /etc/passwd || die "no passwd file"
#    This works in subshells and loops, but may not exit with
#    a code other than 0.

die () {
    echo "$tag: $*" >& 2
    exit 1
}

# usage: prints an optional string plus part of the comment
#   header (if any) to stderr, and exits with code 1.

    lines=`egrep -n '^# (NAME|AUTHOR)' $0 | sed -e 's/:.*//'`
