__NOTOC__


Acronyms are horrible things - they tend to create a layer of obfuscation that confuses new users, allows knowledge and understanding to diverge from reality as original meanings get lost and forgotten, and can be used by some to imply some kind of knowledge superiority over their peers.  Unfortunate they are rife in IT (!), and systems and techniques are often given unnecessarily long or complex names in order to create a ''good'' acronym...
