grahams_snippets: Graham's snippets (and other Pivot stuff)

This low volume list is used only to announce any new snippets which Graham codes for the Pivot blogging system (http://www.pivotlog.net/), or updates to existing snippets.

The list is one-way only; discussions should be confined to the Pivot forums.

Expect to receive no more than one or two mails per month; sometimes not even that many.
