Affix comes with a set of command-line utilities that provide the functionality an end-user needs. However the command line is not always what all people like. Therefore many functions were wrapped into the GUI and made easy to use from the graphical user interface.

Affix Frontend Environment (AFE) is a GTK-based application. GTK, which stands for GIMP ToolKit, is a library for creating graphical user interfaces for the X Window System. In order to compole AFE you need to install libgtk development package. You can download source code and read usage guides in the Affix Frontend Environment page.
