 Users of `pip` can install the Rust extensions with the following command::
 
-  $ pip install mercurial --global-option --rust --no-use-pep517
+  $ pip install mercurial \
+        --global-option \
+        --rust \
+        --no-use-pep517 \
+        --no-binary mercurial

 the legacy `setup.py` system. Mercurial has not yet migrated its complex setup
 to the new system, so we still need this to add compiled extensions.
