+@uref{http://www.python.org/dev/peps/pep-0008/}
+
+@itemize
+@item
+use 4 spaces per indentation level
+
+@item
+never mix tabs and spaces (for indentation)
+
+@item
+Code indented with a mixture of tabs and spaces should be
+converted to using spaces exclusively
+
+Once this is done, we should add @code{python -tt} to the build
+system to avoid such errors in the future.
+
+@end itemize
+
+There should be absolutely no tab characters for indentation in
+any @code{.py} file in lilypond git. All such files should be
+converted to use spaces only.
