' UNIX Tarball creator
' ====================
' Author: Chris Read
' Version: 1.0.1
' ====================
'
' This class provides the ability to archive multiple files together into a single
' distributable file called a tarball (The TAR actually stands for Tape ARchive).
' These are common UNIX files which contain uncompressed data.
'
' So what is this useful for? Well, it allows you to effectively combine multiple
' files into a single file for downloading. The TAR files are readable and extractable
' by a wide variety of tools, including the very widely distributed WinZip.
'
' This script can include two types of data in each archive, file data read from a disk,
' and also things direct from memory, like from a string. The archives support files in
' a binary structure, so you can store executable files if you need to, or just store
' text.
'
' This class was developed to assist me with a few projects and has grown with every
' implementation. Currently I use this class to tarball XML data for archival purposes
' which allows me to grab 100's of dynamically created XML files in a single download.
'
' There are a small number of properties and methods, which are outlined in the
' accompanying documentation.
