// Here's how we manage commandlines for builds/configs/targets. It has complexity so writing down here for reference
//
// Involved options:
//		-client
//		-server
//			These denote Client or Server builds - both for executable and cooked data
//		-target=Foo 
//			Foo can be either say EngineTestClient, UnrealGame, etc. Note that UnrealGame is special for content only projects
//			This option has historically not been used, instead being calculated from the above options. However with 
//			more projects having multiple game/editor targets, it is useful to explicitly choose one of those targets
//		-clientconfig=[Debug|Development|Test|Shipping]
//			Used to choose a build configuration for client _and game_ executables
//		-serverconfig
//			Similar but for server executables
//
// In the case of conflicts (-client and -target=UnrealGame) UAT will fail, so we try to detect that earlier and disallow it
//
// Additionally, for code-based projects, 

// However, given how builds are likely to be triggered by the editor, which can let user change the target/config/etc, when
// ExecuteBuild handles the {ProjectPackagingSettings} replacement, it will first look at the existing commandline and not 
// spceify a conflicting mode (commandline overrides PackagingSettings). 
//
