#
# This uses the SQL::Translator package (aka "SQL Fairy") to parse
# a MYSQL schema and diagram the result using GraphViz.
#
# SQL::Translator appears to be pretty good at analyzing SQL, but is
# badly confused about how to format record labels in the "dot"
# language. I should send the author a patch, but simplest solution
# for now is just to whack sqlt-graph's broken output into shape.
#
# On FreeBSD, SQL Fairy is /usr/ports/databases/p5-SQL-Translator.
