%% This is a sample rebar.conf file that shows examples of some of rebar's
%% options.

%% == Artifacts ==

%% Artifacts are files generated by other tools (or plugins) and whose
%% presence is necessary for a build to be considered successful
{artifacts, ["priv/mycode.so"]}.


%% == Erlang Compiler ==

%% Erlang files to compile before the rest. Rebar automatically compiles
%% parse_transforms and custom behaviours before anything other than the files
%% in this list.
{erl_first_files, ["src/mymib1.erl", "src/mymib2.erl"]}.

%% Erlang compiler options
{erl_opts, [no_debug_info,
            {i, "myinclude"},

             "(linux|solaris|freebsd|darwin)", 'HAVE_SENDFILE'},
            {platform_define, "(linux|freebsd)", 'BACKLOG', 128},
            {platform_define, "R13", 'old_inets'}]}.

%% == Dependencies ==

%% type, location and revision).

%% == alias ==

%% When you want a certain combination of operations to be done

%% > rebar3 test
