About

Efax-gtk is a GUI front end for the 'efax' fax program. It can be used to send and receive faxes with a fax modem, and to view, print and manage faxes received. It also has a socket interface to provide 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.
