<?php
// This file defines a set of functions and an associative array.
// The key of the array corresponds to a header in the source
// import file and the value of the array item will be used in
// the creation of the output file.
//
// An exported Outlook file looks like this:
//
// Title<tab>First Name<tab>Middle Name<tab>Last Name<tab>...
// <tab>Patrick<tab><tab>Walsh<tab>...
//
// Where the first line explains each optional field.  This is what
// will be looked up in the key.
//
// The array need not be in any order and any fields not defined will
// not be transferred.  If the val='+', the value will be appended to
// the previous field and any text after the '+' will be appended 
// before the value.  For example, the following would add a comma and
// a space between LastName and FirstName and store it in FullName:
//
//	array("LastName" => "FullName","FirstName" => "+, ");
//
// Also start with a '#' symbol and a comma separated list will be
// turned into a number of the same entries.
