+All reST files use an indentation of 3 spaces; no tabs are allowed.  The
+maximum line length is 80 characters for normal text, but tables, deeply
+indented code samples and long links may extend beyond that.  Code example
+bodies should use normal Python 4-space indentation.
 
 Make generous use of blank lines where applicable; they help grouping things
 together.
