+# Normally IniFile tries to be clever about detecting number values in the file
+# and casting them to Integers and Floats. This breaks on a value like
+# 048723829744, becuase Integer() tries to treat that as an octal, but fails
+# since it includes 8s and 9s, but Float(048723829744) treats it like a decimal
+# and returns 48723829744.0. Even if Integer() didn't fail it would drop the
+# leading zero. We need to just treat these values as strings, so this gets
+# rid of the fancy typecasting.
