|
|
# 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 time it takes to execute the command in the OUTPUT_FILE, using
|
|
# utility for time measure specified with TIME_CMD option.
|
|
#
|
|
