I've got over 50 projects to build.

I've created a MasterBuild project, and added every project using "Insert project into workspace".

What is the easiest way to AUTOMATICALLY check whether any of the builds had ERRORs? I know I can visually inspect the build output, but even then I could miss the relevant information because of all the other output.

OR...

Is it preferable to use a series of NMAKEs in a BATCH file to build everything?
