+The above are "shortcuts" in the main makefile. The real android makefile is
+`Makefile.android`. Some operations might have to be performed using that one.
+For instance to clean and rebuild all libraries:
+
+ make -f Makefile.android clean-libs
+ make -f Makefile.android libs
+
+Or to monitor the android log stream:
+
+ make -f makefile.android logcat

+PC version build
+----------------
+On UNIX and windows under msys2, just type `make`. No external dependencies are
+needed, everything is included in the source tree.
+
+For msys2 builds, start either a "mingw32 console" or a "mingw64 console", to
+have the environment set up correctly to build native 32bit or 64bit binaries.
+Do not start an "msys2 console"; that's for building with the UNIX system call
+emulation layers linked to the binary (similar to old cygwin).
+
+Alternatively msvc2022 project files are included, configured to build for
+64bit x86. Warning: msvc project files might be out of date. If you encounter
+unresolved symbols, make sure to add any new source files to the project.
