Installing fax4CUPS is very easy:

0. Install efax (http://www.cce.com/efax/).

1. Install the man page.

2. Install the fax script in the CUPS backend directory, for instance,
/usr/lib/cups/backend/; you can look at the first lines of the file for
configurable parameters.

3. Install the PPD file in the CUPS model directory, for instance,
/usr/share/cups/model, and create a new printer using the fax backend (see the
man page).

4. Restart the CUPS daemon (usually "/etc/rc.d/init.d/cups restart" as root
will do the job).
