# NOTES
#
# When working on async_nif.h there are two thigns to remember:
#  1. clang++ provides better error messages
#  2. `rebar compile` doesn't know that eleveldb.cc depends on async_nif.h
#     and so it doesn't recompile that file.
#
# My (greg@basho.com) workaround is to build using this command:
# touch c_src/eleveldb.cc && CXX=clang++ ./rebar compile
