# Class dUnzip2 v2.4
#
# Author: Alexandre Tedeschi (d)
# E-Mail: alexandrebr at gmail dot com
# Londrina - PR / Brazil
#
# Objective:
# This class allows programmer to easily unzip files on the fly.
#
# Requirements:
# This class requires extension ZLib Enabled. It is default
# for most site hosts around the world, and for the PHP Win32 dist.
#
# To do:
# * Error handling
# * Write a PHP-Side gzinflate, to completely avoid any external extensions
# * Write other decompress algorithms
#
# If you modify this class, or have any ideas to improve it, please contact me!
# You are allowed to redistribute this class, if you keep my name and contact e-mail on it.
