Archive supplied URLs in WebCite & Internet Archive.
archiver is a daemon which will process a specified text file, each line of which is a URL, and will (randomly) one by one request that the URLs be archived or spidered by http://www.webcitation.org, http://www.archive.org, and http://www.wikiwix.com for future reference. (One may optionally specify an arbitrary sh command like wget to download URLs locally.)
Because the interface is a simple text file, this can be combined with other scripts; for example, a script using Sqlite to extract visited URLs from Firefox, or a program extracting URLs from Pandoc documents. (See http://www.gwern.net/Archiving%20URLs.)
For explanation of the derivation of the code in Network.URL.Archiver, see http://www.gwern.net/haskell/Wikipedia%20Archive%20Bot.
