 =head1 DESCRIPTION
 
-libhivex is a library for extracting the contents of Windows Registry
+Hivex is a library for extracting the contents of Windows Registry
 \"hive\" files.  It is designed to be secure against buggy or malicious
 registry files.
 
-Unlike many other tools in this area, it doesn't use the textual .REG
-format for output, because parsing that is as much trouble as parsing
-the original binary format.  Instead it makes the file available
-through a C API, or there is a separate program to export the hive as
-XML (see L<hivexml(1)>), or to navigate the file (see L<hivexsh(1)>).
+Unlike other tools in this area, it doesn't use the textual .REG
+format, because parsing that is as much trouble as parsing the
+original binary format.  Instead it makes the file available
+through a C API, and then wraps this API in higher level scripting
+and GUI tools.
+
+There is a separate program to export the hive as XML
+(see L<hivexml(1)>), or to navigate the file (see L<hivexsh(1)>).
+There is also a Perl script to export and merge the
+file as a textual .REG (regedit) file, see L<hivexregedit(1)>.
+
+If you just want to export or modify the Registry of a Windows
+virtual machine, you should look at L<virt-win-reg(1)>.
+
+Hivex is also comes with language bindings for
+OCaml, Perl and Python.
