Hi Bernardo ,
the translation process is very perfect ^_^ and the result is very good thank you for your great efforts to  perform this 

I think there is some problem  the parameters in the URL I fell like its not standard how could we solve this ? 

I mean if some one go to Patrons & Circulation in the main manual : 
http://manual.koha-community.org/3.8/en/patscirc.html
the end of the url is : patscirc.html

but in our work
http://es.koha-community.org/manual/files/ar/ch01s03.html
 is : ch01s03.html

I mean in the future we may have to take user to online help in his language so this may could be done easily by make the lang code variable in the our example : 
  http://manual.koha-community.org/3.8/ar/patscirc.html

have to take the user to Patrons & Circulation in the Arabic manual and 
  http://manual.koha-community.org/3.8/es/patscirc.html

to the Spanish one 

so I think the problem may about how we are generating the html files 

I sent this to the translation and doc mailing list to encourage more people to translate manual to their languages 


Best wishes
