aoqi@0: #
aoqi@0: # This shell script is supposed to be set as a replacement for SHELL in make,
aoqi@0: # causing it to be called whenever make wants to execute shell commands.
aoqi@0: # The <shell command line> is suitable for passing on to the old shell, 
aoqi@0: # typically beginning with -c.
aoqi@0: #
aoqi@0: # This script will make sure the shell command line is executed with 
aoqi@0: # OLD_SHELL -x, and it will also store a simple log of the the time it takes to
aoqi@0: # execute the command in the OUTPUT_FILE, using the "time" utility as pointed 
aoqi@0: # to by TIME_CMD. If TIME_CMD is "-", no timestamp will be stored.
