* This module gives external access to the functions needed to create
* and use XML::LibXML::Nodes from C functions. These functions are made
* accessible from Perl to have cleaner dependencies.
* The idea is to pass xmlNode * pointers (as typemapped void *) to and
* from Perl and call the functions that turns them to and from
* XML::LibXML::Nodes there.
*
* Be aware that using this module gives you the ability to easily create
* segfaults and memory leaks.
