Microsoft Command-line Compiler (cl.exe) Setup:

1. Added to Path, C:\Program Files\Microsoft Visual Studio 8\VC\bin
2. Added to Path, C:\Program FIles\Microsoft Visual Studio 8\Common7\IDE
3. Added to $LIB, C:\Program Files\Microsoft Visual Studio 8\VC\lib

Phoenix Compiler (c2.exe) Setup:

1. Added to $PATH, C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin
2. Added to $PATH, C:\PhoenixRDK\bin\managed\release

Using the Phoenix Compiler:

1. Look at the documentation, C:\PhoenixRDK\doc\PhxDoc
2. Look at the entry, Phoenix-Based Tools::Using Phoenix Compilers::c2 Native Compiler::Running the c2 Compiler
3. Look at the entry, Phoenix-Based Tools::Customizing the Phase List::Specifying Options for an Plug-In

Building Samples:

1. Documentation, C:\PhoenixRDK\src\Samples\README.TXT, didn't help
2. C:\PhoenixRDK\src\Samples\buildsample.cmd seems to work (builds many samples)

Using a plug-in (XML-plug-in):

XML-plug-in -- A plug-in that dumps IR from selected phases as XML. 
Documents how to write a plug-in, and to traverse instructions and their operands by 
basic block.

1. Created test program, C:\PhoenixTest\test.cpp
2. Execute "cl -B2c2.exe -d2plugin:C:/PhoenixRDK/obj/managed/release/XML-plug-in.dll test.cpp"
3. Look at cryptic XML files in current working directory
