slackbuilds_ponce/network/efax-gtk

It is a GTK+ front end for the efax program who 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. It is specially nice for a single user's use, as probably he/she
doesn't usually need a fax server (i.e. hylafax).

See README.SLACKWARE file in efax-gtk's docs directory for configuration
notes.

This requires c++-gtk-utils.
