prepare a Bash shell script, makemake.sh, that will create a makefile called Makefile based on all the .cpp files in the current directory. If a .cpp file has any #includes of non-system header files (those with double quotes around them), then those files should be listed in its dependencies. The -Wall -ansi, and -g options will always be used with g++. The shell script takes the name of the executable as its first argument. If no argument is provided, the script should report the error, and print a usage statement. All other parameters are additional options that should be used with every call to g++. The Makefile should end with a "clean:" routine that removes the executable and all object files.  (Hints: the -n option of echo inhibits the default newline, and t and n work with echo. I used sed and awk to get at the  name of the header files within the .cpp files.)
