|  | # Downloads the ia32 and x64 Debian jessie sysroot that chromium uses, | 
|  | # Only tested and used on Ubuntu trusty linux. Used to keep glibc version low. |

|  | # After running this, source set_ia32_sysroot.sh or set_x64_sysroot.sh, in | 
|  | # the same working directory, to set the compilation environment variables. | 
|  | # Sourcing a script means running the script with a '.', so that it runs |
