<?php
/**
* Implements the del.icio.us API request for a user's posts,
* optionally filtered by tag and/or date.
* Note that when using a date to select the posts returned, del.icio.us
* uses GMT dates -- so we do too.
*
* del.icio.us behavior:
* - includes an empty tag attribute on the root element when it hasn't been specified
*
* Scuttle behavior:
* - Uses today, instead of the last bookmarked date, if no date is specified
* - returns privacy status of each bookmark.
*
* SemanticScuttle - your social bookmark manager.
*
* PHP version 5.
