+    Kivy Git Pre-Commit Hook to Enforce Styleguide
+    ==============================================
+
+    This script is not supposed to be run directly.
+    Instead, copy it to your kivy/.git/hooks/ directory, call it 'pre-commit'
+    and make it executable.
+
+    If you attempt to commit, git will run this script, which in turn will run
+    the styleguide checker over your code and abort the commit if there are any
+    errors. If that happens, please fix & retry.
+
+    To install::
+
+        cp kivy/tools/pep8checker/pre-commit.githook .git/hooks/pre-commit
+        chmod +x .git/hooks/pre-commit

+#
+# and we could then remove the special handling in python for targets above.
