File: NULL KFax needs documentation, there is currently none. If you wish to take up this todo, please contact kde-doc-english@kde.org to avoid duplicating effort.
There is currently no stub for this item.
KFax seems to more or less dead, no devel - except maintenance - commits since at least 3 years :( Still any users around?
As Burkhard commented (almost) 6 years ago, KFax was unmaintained then and it was officially moved to unmaintained recently: https://websvn.kde.org/?view=revision&revision=1479349 (barely ported to Qt4). Most of the fax formats can be opened through the Okular TIFF backend.
