A simple implementation...

Add translated strings in kloned.conf:

---[ kloned.conf ]---
# choose the language here
lang    it

fr
{
     mettre_a_jour   in french...
}

it
{
     mettre_a_jour   in italian...
}

en
{
     mettre_a_jour   in english...
}
---------------------

Add a lang.h file with all strings defines like #define  
METTRE_A_JOUR   "mettre_a_jour".

Then edit the lang_text() function that return the translated text  
based on the chosen "lang" setting:

---[ lang.c ]---
#include <klone/klone.h>
#include <klone/context.h>

const char *lang_text(const char *id)
{
     u_config_t *sk, *cfg = ctx->config; /* klone config file */
     const char *text, *lang;

     dbg_err_if((lang = u_config_get_subkey_value(cfg, "lang")) ==  
NULL);

     dbg_err_if(u_config_get_subkey(cfg, lang, &sk));

     dbg_err_if((text = u_config_get_subkey_value(sk, id)) == NULL);

     return text;
err:
     return "NOT FOUND";
}
----------------

Your index.kl1 will then look like this:

---[ index.kl1 ]---
<%!
     #include <liblang/lang.h>
%>

<html>
    <body>
          <%= lang_text(METTRE_A_JOUR) %>
     </body>
</html>
-------------------

Using this method you can switch the language without recompiling  
klone using an external configuration file (-f FILE switch) or you can  
embed all translation into the kloned executable. You could also have  
different config file with just one language defined if you want to  
save storage:

	kloned -f kloned-it.conf
	kloned -f kloned-en.conf
	kloned -f kloned-fr.conf

You'll find the proof of concept klone-app attached.
