Programmatically access your Firefox bookmarks

	"""
	A script to automatically export bookmarks from Firefox's SQLite database.

	There does not seem to be a programmatic way to get Firefox to export its bookmarks in
	the conventional HTML format. However, you can access the bookmark information directly
	in Firefox's internal database, which is what this script does.

	Always be careful when working with the internal database! If you delete data, you will
	likely not be able to recover it.
