+"""Extension management for Windows.
+
+Under Windows it is unlikely the .obj files are of use, as special compiler options
+are needed (primarily to toggle the behavior of "public" symbols.
+
+I don't consider it worth parsing the MSVC makefiles for compiler options.  Even if
+we get it just right, a specific freeze application may have specific compiler
+options anyway (eg, to enable or disable specific functionality)
+
+So my basic strategy is:
+
+* Have some Windows INI files which "describe" one or more extension modules.
+  (Freeze comes with a default one for all known modules - but you can specify
+  your own).
+* This description can include:
+  - The MSVC .dsp file for the extension.  The .c source file names
+    are extracted from there.
+  - Specific compiler/linker options
+  - Flag to indicate if Unicode compilation is expected.
+
+At the moment the name and location of this INI file is hardcoded,
+but an obvious enhancement would be to provide command line options.
