 # Usage from makefile:

 #   $(ELOG) $(CC) $CFLAGS -o $@ $<

 #

 # This shell script is used by the build system to print out commands that fail

 # to execute properly.  It is designed to make the "make -s" command more

 # useful.

 #

 # Note that in the example we are sourcing rather than execing the script.

 # Since make already started a shell for us, we might as well use it rather

 # than starting a new one.

 ( exec "$@" ) || {

     echo

     echo "In the directory " `pwd`

     echo "The following command failed to execute properly:"

     echo "$@"

     exit 1;
