Summary:                    ASP.NET functionality broken on Windows platform
Description: 
On Windows, using the Nemerle compiler for ASP.NET pages does not work, and
returns an error of "cannot load assembly with macros `Nemerle.Macros'". 
This problem occurs whether the .NET Framework (using Cassini in this
case) or Mono (XSP2) is used.

I have something of a scattered narrative on
http://nemerle.org/Talk:ASP.NET_%28tutorial%29 that contains a little more
detail, having to do with assembly versioning, and the frustrated results
of my attempts to correct the problem.

This is quite problematic, because compiler needs to find and load
Nemerle.Macros assembly, but it has no clue where to find it. IIS calls
Nemerle.Compiler directly from GAC and the directory with Nemerle.Macros
is not known.

Workaround for this is to specify additional option in configuration
pointing to proper directory:
  <compiler 
    ...
     compilerOptions="/lib:C:\home\nemerle\ncc\out.stage3"
  />

but it is a little bit ugly.

Also, after using this trick compilation starts, but some bug in CodeDom
provider appears (I'm fixing it now).

It works now (trunk in revision 6234) with mentioned compier option
specified in web.config.

I'm not sure if we can do much better, because the path to Nemerle.Macros
depends on installation of compiler (it is not put into the gac).

Why?

We changed this after bug 380. I don't remember exactly what was the
problem, but I guess it was that MS.NET GAC puts every assembly into
completely separate directory - now, compiler needs to load macros at
start, so it must be able to find the Nemerle.Macros.dll (with compatible
version), but if it exists only in GAC, then we can't find it easily.

So we decided to leave Nemerle.Macros.dll in the same dir as ncc.exe, so
when you invoke ncc.exe it can easily locate Nemerle.Macros.dll. You can
try 0.2.9 MSI installer to see the details...

I fixed the documentation. We are not able to do this better at the moment.
Maybe in future we'll find out some better solution.
