   2 # SConscript for swrast convenience library
   3 #
   4 # This is a meta-driver which consists of any and all of the software
   5 # rasterizers into a single driver.  A software rasterizer is defined
   6 # as any driver which takes an sw_winsys pointer as the only argument
   7 # to create_screen.
   8 #
   9 # XXX: unfortunately users of this driver still need to link in any
  10 # extra libraries needed for the particular driver (eg llvm for
  11 # llvmpipe).  Not sure how to get around this.
