# some hints to get you going. as this isnt a totally "open" library, you need
# to do some work. follow the steps below.
#
# 1. if you don't already have a ti account get one here. it's free:
#  http://www.ti.com/hdr_my_ti
# 2. fetch the gl-es bin from here:
#  https://www-a.ti.com/downloads/sds_support/targetcontent/dvsdk/oslinux_dvsdk/v3_00_3530/OMAP35x_Graphics_SDK_setuplinux_3_00_00_06.bin
# (replace version in .bin file as appropriate)
# 3. put the OMAP35x_*.bin file in libgles-omap3/
#  mv OMAP35x_Graphics_SDK_setuplinux_3_00_00_06.bin ./libgles-omap3/
# 
# voila!
