+BUILDING
+==========
+
+1. hg kwarchive __arch
+2. cd __arch
+3. Build the documentation. E.g. with
+
+       (cd docs && gmake html)
+
+   The documentation currently has to be built when the _speedups C extension
+   module is *not* available.
+
+4. python setup.py sdist
+
+5. python setup.py bdist_wheel --pure-only
+
+6. Optional: python setup.py bdist_wheel
+
+7. Binary package for Winwows:
+
+   a) Make the Ninja build-file for your system:
+
+        sh windows-dev/pc01/cross.sh
+
+   b) Cross-compile with:
+
+        ninja -f _build-win-amd64.ninja
+
+      Needs currently LLVM-11.
+
+   c) Make the resulting DLL available to setup.py:
+
+        cd configmix && ln -s ../build/_builddir-win-amd64/out/_speedups.pyd _speedups.pyd
+
+   d) python setup.py bdist_wheel --windows-cross-pack -p win_amd64
