This program is a Gtk+/Gtk-- front end for the efax program for receiving and sending faxes with a fax modem. To use it you must have efax and ghostscript installed, and the executables (efax, efix and gs) must be situated in the default system path. Any files to be faxed must be in postscript format, which is the generic printer format for Unix/Linux systems. The program will use ghostscript to convert these into the Group 3 fax format which the fax modem will understand.
