dnl Process this file with autoconf to produce a configure script.
dnl The ONLY thing this is used for is to configure for different
dnl linux architectures and configurations, it is not used to make the
dnl code more portable

dnl You MUST have an environment that has all the POSIX functions and
dnl some of the more populare bsd/sysv ones (like select). You'll also
dnl need a C++ compiler that is semi-standard conformant, exceptions are 
dnl not used but STL is.

dnl 'make -f Makefile startup' will generate the configure file from 
dnl configure.in correctly and can be run at any time
