Synopsis

This header file encapsulates many generally-useful include files and defines lots of good stuff. The intention of this header file is to hide the messy #ifdef's that you typically need to make real programs compile & run. To use, specify as the first include file in your program. The main contributors to this file were:

PH	Pieter Hintjens <ph@imatix.com>
EDM	Ewen McNeill <ewen@imatix.com>
PA	Pascal Antonnaux <pascal@imatix.com>
BW	Bruce Walter <walter@fortean.com>
RJ	Rob Judd <judd@alphalink.com.au>
