# to build: 
# make prepare; make libhttp

# set this beforehand if you use clang
# make sure to preset CFLAGS if you use non-ix86 platform
# or non-GNU-compat C compilation system
# Uncomment these if you're on a 32-bit Linux?
# CC = cc
# CFLAGS = -Ofast -march=nocona -mfpmath=sse

# if you have local copies of libs in this folder,
# try LIBS=-L. (other stuff here)
