[darwinbuild-dev] How to find build version difference

Michael's plugin is a good start, however copying the whole Build  
plist (with all project attributes) to inspect it is a rather  
heavyweight process.  It's possible to use the plugin API to search  
the data in the sqlite database.  The use of this API also answers the  
question below.

CFArrayRef DBCopyProjectNames(CFStringRef build);

This function returns an array of all projects in the given build  
(including inherited projects).  I believe this is already sorted, but  
I'm not 100% sure.

There's also the following function which you might be interested in:

CFArrayRef DBCopyChangedProjectNames(CFStringRef oldbuild, CFStringRef  

Also it's not clear to me why DBSetPlist() is called at the end... I  
don't think of "diff" as a mutagenic operation.
