# Example makefile with compilier warnings and automatic rules for a single
# executable composed of a lst of sources and headers. Rename this file to 
# Makefile and edit the variables defined under "EDIT THIS SECTION" 

# Build executable with:
# % make
# Delete object files and executable with:
# % make clean
# Rebuild all objects and executable with:
# % make -B

# See the Manual (% man make) for more information
