+ * Rational of XBT_PUBLIC:
+ * * This is for library symbols visible from the application-land.
+ * Basically, any symbols defined in the include/directory must be
+ * like this (plus some other globals).
+ *
+ * UNIX coders should just think of it as a special way to say "extern".
+ *
+ * * If you build the DLL, define the DLL_EXPORT symbol so that all symbols
+ * actually get exported by this file.
+
+ * * If you do a static windows compilation, define DLL_STATIC, both when
+ * compiling the application files and when compiling the library.
+ *
+ * * If you link your application against the DLL or if you do a UNIX build,
+ * don't do anything special. This file will do the right thing for you
+ * by default.
+ *
+ *
+ * Rational of XBT_EXPORT_NO_IMPORT: (windows-only cruft)
+ * * Symbols which must be exported in the DLL, but not imported from it.
+ *
+ * * This is obviously useful for initialized globals (which cannot be
+ * extern or similar).
+ * * This is also used in the log mecanism where a macro creates the
+ * variable automatically. When the macro is called from within SimGrid,
+ * the symbol must be exported, but when called from within the client
+ * code, it must not try to retrieve the symbol from the DLL since it's
+ * not in there.
+ *
+ * Rational of XBT_IMPORT_NO_EXPORT: (windows-only cruft)
+ * * Symbols which must be imported from the DLL, but not explicitely
+ * exported from it.
+ *
+ * * The root log category is already exported, but not imported explicitely
+ * when creating a subcategory since we cannot import the parent category
+ * to deal with the fact that the parent may be in application space, not
+ * DLL space.
