# Usage: sh shell-tracer.sh <TIME_CMD_TYPE> <TIME_CMD> <OUTPUT_FILE> <shell command line>
#
# This shell script is supposed to be set as a replacement for SHELL in make,
# causing it to be called whenever make wants to execute shell commands.
# The <shell command line> is suitable for passing on to the old shell,
# typically beginning with -c.
#
# This script will run the shell command line and it will also store a simple
# log of the the time it takes to execute the command in the OUTPUT_FILE, using
# utility for time measure specified with TIME_CMD option.
#
# Type of time measure utility is specified with TIME_CMD_TYPE option.
# Recognized options values of TIME_CMD_TYPE option: "gnutime", "flock".
