+applications that deal with the Internet.
+
+Among the supported modules, the most commonly used implement the
+SMTP (sending e-mails), HTTP (WWW access) and FTP (uploading and downloading
+files) client protocols.  These provide a very natural and generic interface
+to the functionality defined by each protocol.  In addition, you will find
+that the MIME (common encodings), URL (anything you could possible want to do
+with one) and LTN12 (filters, sinks, sources and pumps) modules can be very
+handy.")
