Continuous integration

[ChrisF]

I'm playing with the ContinuousIntegration.bld file from the sample folder, and using Starteam in my case. I see where the script knows that it has not run yet, and so it sets a NEED_TO_BUILD macro to true. After the first build, it runs a Starteam History command for missing and out-of-date files, but I don't see where it uses this information to set the NEED_TO_BUILD macro to either true or false. When I test it, it always builds, regardless if any check ins were done so I'm confused. Thanks!
