The Mono (and MS.NET) runtime automatically retargets these assemblies.

This is accomplished using the following <startup> node in NAnt.exe.config:

    <startup>
        <!-- .NET Framework 2.0 -->
        <supportedRuntime version="v2.0.50727" />
        <!-- .NET Framework 2.0 Beta 2 -->
        <supportedRuntime version="v2.0.50215" />
        <!-- .NET Framework 2.0 Beta 1 -->
        <supportedRuntime version="v2.0.40607" />
        <!-- .NET Framework 1.1 -->
        <supportedRuntime version="v1.1.4322" />
        <!-- .NET Framework 1.0 -->
        <supportedRuntime version="v1.0.3705" />
    </startup>

As a result, we can have a single binary distribution that runs natively on
.NET 2.0 / Mono 2.0 profile and can still run on .NET 1.1 / Mono 1.0 profile
and .NET 1.0.

I really appreciate the work you're doing, but wouldn't it be best if we
(the NAnt team) would release the RPM's ?

(same goes for NUnit, ...)

Wouldn't it be better to have the Mono team would share knowledge
(instructions, best practices, ...) and perhaps coordinate the efforts of
other projects.
