How to use this script:

1. Adjust the variables in the beginning of the script.

2. To make a clean PNaCl build of UAE, execute
       ./build_native_client.sh pnacl

3. Start the web server, e.g., by executing
       python -m SimpleHTTPServer 8080
   from the web server destination dir.

4. To stage the files and run Chrome do
       ./build_native_client.sh run

5. Do incremental builds with
      ./build_native_client.sh incremental

6. To run and make Chrome/PNaCl wait until a NaCl debugger is attached use
       ./build_native_client.sh run
