I'm using erlang distribution which came with Ubuntu 11.04. I'll
upgrade to 11.10 as soon as I get time.

I tried with /code directory, but I get an error:

:~/code/egon_server/releases$ erl
Erlang R13B03 (erts-5.7.4) [source] [smp:4:4] [rq:4] [async-threads:0]
[hipe] [kernel-poll:false]

Eshell V5.7.4  (abort with ^G)
3> {ok, Conf1} = file:consult("egon_server.0.1.config").
{ok,[{sys,[{lib_dirs,["/home/nick/code/"]},
           {rel,"egon_server","0.1",[kernel,sasl,stdlib,egon_server]},
           {boot_rel,"egon_server"},
           {relocatable,true},
           {profile,standalone},
           {app,egon_server,[{vsn,"0.0.1"},{debug_info,keep}]}]}]}
4> {ok, Spec} = reltool:get_target_spec(Conf1).
** exception error: no match of right hand side value {error,
                                                       "Mandatory
application kernel is not included in []"}

Cheerz,
