\section{\pako --- Introduction and Overview}


\label{sec-introduction}

After this introduction follows section \ref{sec-perplexed},
a ``Guide for the Perplexed''.  Here 
we briefly explain some general features of \pako\ as well as differences from
the previous control system for the \thirtyM.

In Section \ref{sec-merienda} we give a very short recipe with the bare minimum
to get started with Heterodyne observations.

Section \ref{sec-cookbook},
is ``PaKo's Cook Book''. It is meant to evolve into a
gentle step-by-step and command-by-command explanation of how to do
observations with the NCS.

Next is the ``NCS User's Guide'', \ref{sec-guide},
which follows the same outline
as the ``Cook Book'', but includes more details.   The examples
included here are all in the form of \pako\ command language scripts.

The section ``\NCS\ Explained'', \ref{sec-explained},
 contains detailed explanations
of some aspects of the NCS.

Finally, the ``\pako\ Language Internal Help''  is reproduced 
in section \ref{sec-help}.

A lot of information is intentionally duplicated in different sections of this
manual, so that, e.g., the ``Cook Book'' and the ``User's Guide'' can be read
independently.  It should not be necessary to read all sections in this
manual!  Also much space is taken up by examples, so the actual text
to read is not very long!

We recommend that all users who face the NCS for the first time
should read the ``Guide for the Perplexed''.
Beginning observers and those who like to set up their observations
one command at a time can then follow the ``Cook Book'', section
\ref{sec-cookbook}.

More experienced observers may prefer the ``User's Guide'',
section \ref{sec-guide},
especially those who need more advanced options and those who like 
to prepare scripts with the specifications of their observations
(recommended!).

All users may want to consult the section \ref{sec-explained}
``NCS explained''  for general information, 
or look up details in the \help\ section, \ref{sec-help},
which is a complete reference for all commands and options.

Before starting observations, users should also review the up-to-date
notes on the NCS wiki pages at: \hfil\break
