Please study make manual page in detail . There are many more commands to be
applicable ,
for example  ( .include ) which you may use to include the original make
file name Makefile at any suitable point in your own make file .


Also studying the currently used Makefile files in FreeBSD may give many
ideas to apply .

Thank you very much .
