# By default, builds optimized 32bit libbloom (under ./build)
# Requires GNU Make, so invoke appropriately (make or gmake)
#
# Other build options:
#
#   DEBUG=1 make        to build debug instead of optimized
#   MM=-m64 make        to build 64bit library
#
# Other build targets:
#
#   make test           to build and run test code
#   make gcov           to build with code coverage and run gcov
#   make lint           to run lint
#   make clean          the usual
