Nemerle.Compiler.Utils.csproj not support completion, hints, code navigation
and not full syntax highlighting. Really it is a C#-project with small hack
in project stricture (VS project in fact is MSBuild script). It hack enables
us: simple code highlighting, project support and debugging. We while use
just it. It happens because VS Integration is not done (not stabile).
Nemerle.Compiler.Utils.nproj - is wrapper which help open
Nemerle.Compiler.Utils.csproj under ours VS Integration. It's project really
empty. It contains only reference to Nemerle.Compiler.Utils.csproj.
When VS Integration will be work properly we move to
Nemerle.Compiler.Utils.nproj and remove the Nemerle.Compiler.Utils.csproj.

Note: Meanwhile Nemerle.Compiler.Utils.nproj work only if it run under
experimental HIVE of VS 2005. For it you must open
Nemerle.VsIntegration.csproj project properties and find Debug tab. Set
"Start external program:" field to
<%VS80COMNTOOLS%..\..\Common7\IDE\devenv.exe>. Set <Command line arguments:>
field to </rootsuffix Exp>.
It describe in
http://rsdn.ru/article/nemerle/Nemerle.VsIntegration-en.xml mage. We update
it.

It's true. Completion supported only by .nproj which run with /rootsuffix
Exp.

You must open Nemerle.Compiler.Utils.nproj. And VS must be run as I describe
above.

VS support editing single .n files, but it no give project support.

The bugs in this mode will fix later.
