Possible targets are `macro`, `neko`, `js`, `php`, `cpp`, `flash9`, `as3`, `java`, `cs`, `python`, and `third-party`. However, `flash9`, `as3`, and `third-party` are not likely to work on local machines (TODO).

 Note that the script will try to look for test dependencies and install them if they are not found. Look at the `getXXXDependencies` functions for the details.
