+When certain blocks of code need to cope with API changes in core Mercurial,
+they should have comments in the ``hg <= x.y (commit hash)`` format. For
+example, if a function needs another code path because of changes introduced in
+02802fa87b74 that was first included in Mercurial 5.3, then the comment should
+be::
+
+    # hg <= 5.2 (02802fa87b74)
+
+See also tests/test-check-compat-strings.t.
