+=head1 DESCRIPTION
+
+This script will connect to an IMAP server, login and then monitor the user's
+INBOX. When new messages arrive it will extract the From address and Subject
+from the message and compose a message to be used by "Google Talk" to announce
+the email. The message will be similar to:
+
+  "<From> emailed <Subject>"
