 Nmap offers more than a hundred
 command-line options, although many are obscure features or debugging
 controls that most users can ignore.  Many graphical frontends have been
-created for those users who prefer a GUI interface.  Nmap has traditionally included a simple GUI for Unix named <application>NmapFE</application><indexterm><primary>NmapFE</primary></indexterm>, but that was replaced in 2007 by Zenmap, which we had been developing since 2005.

Nmap has traditionally included a simple GUI for Unix named <application>NmapFE</application><indexterm><primary>NmapFE</primary></indexterm>, but that was replaced in 2007 by Zenmap, which we had been developing since 2005.  Zenmap is far more powerful and effective than NmapFE, particularly in results viewing.  Zenmap's tab-based interface lets you search and sort
 results, and also browse them in several ways (host details, raw Nmap
 output, and ports/hosts).  It works on Microsoft Windows, Linux, Mac
 OS X, and other platforms.  Zenmap is covered in depth in <xref linkend="zenmap"/>.  The rest of this book focuses on command-line invocations of Nmap.
