    This file is part of the gemini and fixflow skins for pmwiki 2.

    This script sets the default styles for gemini or fixflow skins.
    It also defines various style options. All options are loaded via seperate css files,
    one each for colors, fonts, rightbar settings and alternative layouts.  
        
    To set different styles than the defaults it uses stylechange.php.
    For switching styles the following are used, which set cookies :
    ?setcolor=..., ?setfont=..., ?setrb=..., setlayout=..., ?setmenu=..., ?setsidebar=....
    The following can be used to change a style for a page, without seting  a cookie:
    ?colors=..., ?fonts=..., ?rb=..., ?layout=... ?menu=... ?sidebar=...
    The possible parameters are defined below in various lists.
      
    By default, the cookies that are created will expire after
    one year.  To have cookies to expire at the end of the browser
    session, set $FontCookieExpires=0; $ColorCookieExpires=0; 
    $RightbarCookieExpires=0; $LayoutCookieExpires=0;
