In both the `simple' and `power' searching modes, you will be asked to 
answer a short sequence of questions as below.  Once you have entered
the details of your query the program will try and find the entry for
which you are looking.  You will be prompted to enter:

:- the NAME of the person for whom you are seeking information
:- their DEPARTMENT (optional), 
:- the ORGANISATION they work for, and 
:- the COUNTRY in which the organisation is based.

On-line HELP is available to explain in more detail how to use the
Directory Service.  Please type ?INTRO (or ?intro) if you are not familiar 
with the Directory Service.

?          for HELP with the current question you are being asked
??         for HELP on HELP - lists the various help screens available
q          to quit the Directory Service (confirmation asked unless at the
           request for a person's name)
Control-C  abandon current query or entry of current query

The following sections explain the `simple' and `power' modes, and when one
mode may be preferable.  Note that you can switch between modes between 
queries.

Simple Look-ups
---------------
This is the best mode if you are looking for a specific person, department
or organisation, although some browsing is also possible if you can't initially
find the entry for which you are looking.  You will be offered a small number
(3 or 4) of prompts to identify the entry you wish to find.  Once you have 
selected this mode of querying there are large number of help screens 
available to guide you if you need help.  If the information is available, 
the results should be delivered within seconds.

You can select this mode by typing the letter `s' at the prompt for a person's
name.

Powerful, multiple organisation searches
----------------------------------------
This mode should be selected when you know the name of a person and the 
country in which they work, but do not know the name of the organisation.
The program will either search all the organisations which loosely match the 
string of characters entered, or will search all organisations in a country
if the organisation name is omitted entirely.  This is brute force searching 
and takes longer than simple look-ups, although it can be surprisingly quick 
as many organisations can be searched simultaneously.

You can select this mode by typing the letter `p' at the prompt for a person's
name.
