It seems like VS should make it easy to integrate help for a class lib into your current project.  For example...  If I'm using a class library that has a chm help file, there should be a way to include a reference to the help file for the project.  This way I can access the chm from inside VS when working on that project.   For other projects, that don't use this class lib, the help file would not be included in lookups.  
 
It would be really neat if the class lib could include a reference to it's help file so that VS could make this all happen automatically.  Maybe this is planned in VS 2005....
