+# ----------------------------
+#
+# (C)2005 MySQL AB
+#
+#
+# The purpose of this tool is to work out storage requirements
+# from an existing MySQL database.
+#
+# This involves connecting to a mysql server and throwing a bunch
+# of queries at it.
+#
+# We currently estimate sizes for: 4.1, 5.0 and 5.1 to various amounts
+# of accurracy.
+#
+# There is no warranty.
+#
+# BUGS
+# ----
+# - enum/set is 0 byte storage! Woah - efficient!
+# - some float stores come out weird (when there's a comma e.g. 'float(4,1)')
+# - no disk data values
+# - computes the storage requirements of views (and probably MERGE)
+# - ignores character sets.
