annotate scripts/schema_diagram.py @ 6354:b61de764c8cc
Remove left over python style config remnant, doc update.
Replace three with two as there are only two items in the list.
Remove setting that was used in the code for python style init files.
Support for python style init files removed a while ago and were
deprecated in 0.8 timeframe IIRC.
