Since it is open source, we can get the code. To start look at: http://dev.chromium.org/developers/how-tos/getting-started is a link for developers.

It is for Windows only for now. The have an plug in for Visual Studio. It would be nice to have an eclipse section.

These commands will get it via the command line interface:
wget http://build.chromium.org/buildbot/archives/chromium.tgz
wget http://build.chromium.org/buildbot/archives/depot_tools_win.zip

The source code is 437 M. The depot tools is much smaller.
