Makefile

# remembyte Makefile
# 
# Override variables on the commandline or by creating a new Makefile that
# includes this one.
#
# You can override them on the commandline like so: 
#     CCINCLUDES=-I/path/to/extra/include/dir
#     CCLIBS=-L/path/to/extra/lib/dir
#
# You can override them in a new Makefile by creating a file like this:
#     CCINCLUDES=-I/path/to/extra/include/dir
#     CCLIBS=/path/to/extra/lib/dir
#     include Makefile
# Save the new Makefile in this directory and invoke make with the `-f` flag:
#     make -f ./new_Makefile.txt
