Gwatch is mail spool monitor similar to the watcher feature of tkrat. Gwatch monitors a mail spool, and when new mail arrives, it displays a window, containing the from, and subject fields of the new email. It is written in C, with the GTK+ toolkit, and developed on Linux. It is known to compile and work on FreeBSD, and should compile and run on most *nix platforms (see the Build Notes in the documentation). Note: Gwatch is still in the ALPHA stage. It may break at any time.
