Manager class

It seems that meantime the GlobalEnv stuff changed so I cannot 
initialize the LexerColorizer anymore.

It was:
           LibraryReferenceManager.LoadMacrosFrom(@"c:\program 
files\nemerle\Nemerle.Macros.dll");
           GlobalEnv.Init();

Now it gives errors. To what shall I change this?
C:\Program Files\Visual Studio 2005 
SDK\2006.04\VisualStudioIntegration\Samples\NemerleIntegration\LanguageService\PythonScanner.cs(9,4): 
error CS0122: 'Nemerle.Compiler.LibraryReferenceManager' is inaccessible 
due to its protection level
C:\Program Files\Visual Studio 2005 
SDK\2006.04\VisualStudioIntegration\Samples\NemerleIntegration\LanguageService\PythonScanner.cs(9,28): 
error CS0117: 'Nemerle.Compiler.LibraryReferenceManager' does not 
contain a definition for 'LoadMacrosFrom'
C:\Program Files\Visual Studio 2005 
SDK\2006.04\VisualStudioIntegration\Samples\NemerleIntegration\LanguageService\PythonScanner.cs(10,14): 
error CS0117: 'Nemerle.Compiler.GlobalEnv' does not contain a definition 
for 'Init'


Another change in:
           NC.LexerString lexer = new 
Nemerle.Compiler.LexerString(NC.ManagerClass.Instance, req.Text, new 
NC.Location(0, 1, 1));
           NC.PreParser preparser = new Nemerle.Compiler.PreParser(lexer);
           NC.Token.BracesGroup braces = preparser.PreParse();


Is "NC.ManagerClass.Instance" a good parameter for for the parser?

I mean shall I implement some Manager class and use that or what? Maybe 
some documentation would not hurt... (I mean maybe 10 lines would suffice)

ps:
I am asking these questions after messing with the source and SVN log 
for 2 hours... :(
