# Usage: make <target> <macros>

# TARGETS:
#   all                  Build a shared so from the whole library
#   clean                Cleanup object files, prepare for rebuild
#   static               Build a static library (*.a)

# MACROS: (make clean before you change one)
#   NOBOOST=1            Build against boost workaround
#   SINGLETHREADED=1     Build single-threaded library
#   DEBUG=1              Build debug build of library
