Java Mail - Pop e-mail and docs from an Inbox

Looking for a cmd line executable and source java program that can read my (or any) gmail inbox and pop e-mails and attached documents. contents of the e-mail? (from, subject, e-mail contents)? should be put into a txt file and the documents should be popped off of the gmail server. The txt file and any corresponding documents should be placed in a directory on the local drive (i.e. c:\temp\) and in a specific folder with a unique name (timestamp and sequence id). Lastly, the cmd line should be able to distinguish whether the e-mail has already been read and if so, it should not re-pop the e-mail(s).? This way the java application can be run several times during the day.
