     @class wxSVGFileDC
 
     A wxSVGFileDC is a device context onto which graphics and text can be
-    drawn, and the output produced as a vector file, in SVG format (see the W3C
-    SVG Specifications <http://www.w3.org/TR/2001/REC-SVG-20010904/>). This
-    format can be read by a range of programs, including a Netscape plugin
-    (Adobe), full details are given in the SVG Implementation and Resource
-    Directory <http://www.svgi.org/>. Vector formats may often be smaller than
-    raster formats.

     The intention behind wxSVGFileDC is that it can be used to produce a file
