Efax-gtk provides a GUI frontend for the efax fax
program. It interfaces with efax directly,
replacing the scripts supplied with efax, and can
be used for receiving and sending faxes, and for
viewing, printing, and managing faxes which have
been received and sent. It also has a socket
interface that provides a "virtual printer" for
sending faxes from word processors and similar
programs, and can automatically e-mail a received
fax to a designated user and automatically print a
received fax.
