+// 1. compile without change --> *include* path error (and others)
+// 2. fix include path error, i.e. adjust the project properties for C/C++ to
+//    also use the local .\inc path for includes
+
+// 3. compile and link --> *compiler* errors
+// 4. fix all *compiler* errors, i.e. fix missing includes in main.c
+
+// 4. compile and link --> *linker* errors
+// 5. adjust the project properties for Linker to also link with the
+//    library lib\read_write.lib
+
+// 6. compile and link --> fix remaining errors if any
+
