1.28 +# Usage: sh shell-tracer.sh <TIME_CMD> <OUTPUT_FILE> <OLD_SHELL> <shell command line>
1.29 +#
1.30 +# This shell script is supposed to be set as a replacement for SHELL in make,
1.31 +# causing it to be called whenever make wants to execute shell commands.
1.32 +# The <shell command line> is suitable for passing on to the old shell,
1.33 +# typically beginning with -c.
1.34 +#
1.35 +# This script will make sure the shell command line is executed with
1.36 +# OLD_SHELL -x, and it will also store a simple log of the the time it takes to
1.37 +# execute the command in the OUTPUT_FILE, using the "time" utility as pointed
1.38 +# to by TIME_CMD. If TIME_CMD is "-", no timestamp will be stored.
