[erlang-questions] Conditional configuration?

[David Welton]

Chicago Boss copies a handy idea from Rails, which copied it from
somewhere else in turn: having different "environments", such as
development, production and testing.

Is it possible to conditionally do things in an Erlang configuration
file?  I get the impression it is not.

What I'd like to accomplish:

 {lager,
  [{error_logger_hwm, 100},
   {handlers,
    [{lager_console_backend, info},
     {lager_syslog_backend,
      ["gsd_web", daemon, info,
       {lager_default_formatter, [date, " ", time, " [", severity, "]
", module, " ", pid, " ", message, "\n"]}
      ]},

%% ^^^^^ only in production mode

     {lager_file_backend, [{file, "log/error.log"}, {level, error}]},
     {lager_file_backend,
      [{file, "log/console.log"},
       {level, info},
       {formatter, lager_default_formatter},
       {formatter_config, [date, " ", time, " [", severity, "] ",
module, " ", pid, " ", message, "\n"]}
      ]}
    ]}

%% ^^^^ runs only in development mod

Ideas on how to best accomplish this?

Thanks
