Parse::Nessus::ENX version 1.1
===============================

DESCRIPTION

This module is designed to extract information from Extended NSR (ENX)
files. Certain functions have been designed to return certain sets of data,
such as service banners and OS versions. Other functions have been
provided that will return more specific information, such as all IPs
listening on a given port or all IPs associated with a specified plugin
id.

To install:

	% perl Makefile.PL
	% make
	% make test
	% make install
