Limitations/TODO :
------------------

 + the HTML pages are checked for links in 
		BODY   background
		IMG    src longdesc
		A      href
		INPUT  scr
		LINK   href
		AREA   href
		FRAME  src longdesc
		IFRAME src longdesc
		SCRIPT src
	  
   to be added : (need at bit more reflexion)
		APPLET codebase/code,archive
		OBJECT codebase/classid,data,archive
		HEAD   profile
	  
 + directory restriction should be more accurate (restrict text/html or all)
 + possibility to download non text/html from other server (??? : hard !)
 + possibility to restrict data upon mime type (should be doable)
 + possibility to pause/resume a download (require some headaches)

 + only one connection to the server at a time ... sloooowwwwww

 + the config file should be a text file and not a python file ...

 * do some operations in C (or C++) to speed up things ...
