It's ok I found it, the rules are in the readme
Code:
             style*.css   // are always loaded and at least ONE should contain site-wide properties.
language_stylesheet.css   // changes to ALL pages, when that language is used
          page_name.css   // changes to one page 
 language_page_name.css   // changes to one page, when that language is used
            c_??_??.css   // changes to all info pages in a category
   language_c_??_??.css   // changes to all info pages in a category, when that language is used
               m_??.css   // changes to a manufacturer's listing page
      language_m_??.css   // changes to a manufacturer's listing page, when that language is used
               p_??.css   // changes to a product's info page
      language_p_??.css   // changes to a product's info page, when that language is used
             print*.css   // printer-friendly global usage site-wide changes for printing-only
Now I just need to get the js issue sorted
