Well I'm getting enjoy it:) Here is the modified version of the skeleton. 
UNfortunately I haven't time to propagate all the necessary changes in the 
source tree, so if any help and contribution is very appreciated.

if (args_info->@address@hidden
    && !(args_info->@address@hidden
@if@ dep_option_is_flag  @then@
        || args_info->@address@hidden
@elseif dep_option_has arg @then@
        || args_info->@address@hidden

    fprintf (stderr, "%s: @option_descr@ option depends on option 
'@dep_option_descr@'%s\n", @package_var_name@, (additional_error ? 
additional_error : ""));
    error = 1;
