We need three new namespace for ne.wikibooks. They are as follows:
'पाकपुस्तक' (Cookbook), 'बालपुस्तक' (Wikijunior) and 'विषय' (Subject)
also their respective talk parts
'पाकपुस्तक वार्ता' (Cookbook talk) 'बालपुस्तक वार्ता' (Wikijunior talk) and 'विषय वार्ता' (Subject talk)
then, we need following aliases with some priority
'Wikibooks' => NS_PROJECT,
'Wikibooks talk' => NS_PROJECT_TALK,
'Cookbook' => 'पाकपुस्तक'
'Cookbook talk' => 'पाकपुस्तक वार्ता'
'Wikijunior' => 'बालपुस्तक'
'Wikijunior talk' => 'बालपुस्तक वार्ता'
'Subject' => 'विषय'
'Subject talk' => 'विषय वार्ता'
and following aliases with lesser priority
'विपु' => NS_PROJECT,
'विपु वा' => NS_PROJECT_TALK,
'प्र' => NS_USER,
'प्र वा' => NS_USER_TALK,
'ढाँ' => NS_TEMPLATE,
'ढाँ वा' => NS_TEMPLATE_TALK,
'श्रे' => NS_CATEGORY,
'श्रे वा' => NS_CATEGORY_TALK,
