Here's an update
Version 1.5a released (May 4th 2007)
Okay, so the chinese developers at BSNL finally made some changes to their site. They changed a column heading from \"Excluding Night Unlimited\" to \"Fee\"! Wow.
Anyways since DUF is a duffer screen scraper, it failed.
Here is the patched version.
It will last only as long as there are no further changes in the BSNL site.
I am beginning to hope that is never ;-)
