[Mono-dev] Heads up: Elimination of the 2.0 and 4.0 profiles

Hey Alex,

It is very repetitive work, so what I wanted to do was to write a perl
script to remove the *obvious* ifdefs.   The tool would remove only those
that match the following criteria (more or less):

   - Remove toplevel #if NET_2_0 with the final #endif
   - Only remove those that contain those preprocessor directives

And then have a human do the more fine-tuned approach.      There are a
couple more defines that I remember could be automated, but I would love to
have this in the form of a script.

I am afraid of applying a patch like that blindly, because there are no
exact guarantees of what happened without reviewing the whole file.  So a
script with the invariants would take a lot of my nervousness out.

Also, when I did it once, I had a setup where I rebuilt the assemblies and
compared the output.  This would ensure that removal of ifdefs did not
change the resulting binaries.
