 | # 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. | 
 | # Creates directories called "build" and "tools" in the current directory. | 
 | # 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 | 
 | # in the current shell, not a subshell, as in: | 
 | #   . sdk/tools/set_ia32_sysroot.sh |
