This doesn't sound right to me. That doesn't mean that it isn't right,
it just sounds weird.
file says that the mono dll files are:
MS-DOS executable PE for MS Windows (DLL) (console) Intel 80386 32-bit
and file thinks that the mono exe files are:
MS-DOS executable PE for MS Windows (console) Intel 80386 32-bit
Now, my understanding is that mono uses these DLL files as libraries,
the EXE files as binaries. Are they compiled from source, or provided as
is for use? If they're not compiled from source, this seems like a
violation of Fedora policies (no binary only bits, please).
Presuming that they are compiled from source, they should be
architecture specific. I did not think that C# was an interpreted
language like python/perl... is it more like Java (runtime)?

Well, there are several questions there:
1. Are the DLLs and EXEs truly architecture independent?
2. Are the EXEs used like binaries? (They certainly seem to be)
3. How much will these mono apps break if we move the EXE location to
%{_bindir}? (In my tests with tomboy, it seems to work fine if i move
the EXE to %{_bindir} and edit the /usr/bin/tomboy wrapper script)
4. How much will mono (and its app) go nuts if we move the DLLs to
to /usr/share ?
4. How much will upstream (and unpackaged mono apps built from source)
go nuts if we move our packaged mono bits out of the fake /usr/lib tree?
Let's leave perl and python out of this for the time being and focus on
mono, where we have the opportunity to do things "correctly" early on,
without several years of baggage and precedence.

Well, to be more specific, they end up in: %{_libdir}/%{name}

I'm hoping this is as clear cut as "DLL == library, EXE == binary".

Man, I really don't think there are easy ways to detect this. Is a
package including a DLL file that exists in another package?

Yeah, thats a huge freaking no-no. That alone should invalidate the
package for Fedora inclusion.

Yeah. It is worth noting that banshee seems to be doing this:
/usr/lib/banshee/hal-sharp.dll
But I don't see anything else using mono(hal-sharp).

Yeah, not that I can think of.
Mmmm, this gives a new meaning to DLL hell. Thoughts?
