Wikipedia has an article about plist files (I think).  What is in WMOGAG
is the sum of my knowledge about plist files.  As far as developing
bundles are concerned I haven't been able to find anything at all about
the role of the plist files;  in some cases the purpose is fairly
obvious in other in probably lies buried in the NGBundleManager.

Yep;  the Apple documentation is about the only documentation worth
mentioning when it comes to Objective-C stuff.  The GNUstep
documentation is almost worthless,  consisting mostly of empty bullet
points.
