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