How to delete a budget?

[Colin Law]

Hi,
I have been experimenting with budgets constructed using File, New,
New Budget.  I now wish to delete those I do not need but I am having
trouble finding how to delete a budget.  (Other than hacking the xml
file that is).  Can someone point me in the right direction?  It is
probably obvious.  I tried the help but a search for budget found no
match, I guess the software is getting ahead of the help.

I am using version 2.2.6 on Ubuntu 8.10
