_use_nacl=1          # Enable Native Client support.
_use_libpdf=1        # Enable Chrome PDF support.
_use_pepperflash=1   # Use Pepper Flash plugin. Depends on Native Client!

## -- Invalid build options (build fails if enabled) -- ##
##########################################################
#_use_system_ffmpeg=0  # Use system ffmpeg libraries when building.
# Doesn't work because of GCC 4.7 headers. If you use 4.6, you can enable it.
_use_clang=0          # Use clang compiler. Results in faster build and smaller chromium.
