How to know the version of Android Source code I download?

[tonysonney]

Hi all,
I am completely new to Android/. I wanted to build Android from source code and I want to build Android 1.5r1. I download the Android code from http://source.android.com/download . I use

repo sync

. But how do I know which version of Android I am syncing my workspace to? Is there a page where can I look to find which is the latest version and which version do I have?

Thanks,
Tony

You can find version_defaults.mk file under build/core. in that PLATFORM_VERSION and SDK_VERSION are defined.

thank you,
