Responsibilities are generally seperated into modules.

profanity.c
===========

Contains initialisation, main loop, and shutdown functions.

Initialisation is loading preferences, initialising any libraries/files/data 
structures used.

The main loop is where the work is done.  It will keep checking for a new
character on the input, if there is one deals with it, if not, goes around the
loop again.

If the character was a newline, the input line is processed, the result of
processing input will either continue (TRUE) or stop (FALSE, if the input 
was "/quit").

Shutting down just involves clearing up resources.

title_bar.c, windows.c, status_bar.c, input_win.c
=================================================

These represent the different windows in Ncurses.

    +----------------------------------------------+
    |  TITLE_BAR                                   |
    +----------------------------------------------+
    |                                              |
    |                                              |
    |  WINDOWS                                     |
    |                                              |
    |                                              |
    +----------------------------------------------+
    |  STATUS_BAR                                  |
    +----------------------------------------------+
    |  INPUT_WIN                                   |
    +----------------------------------------------+

The interface to the UI is all through ui.h, all UI modules share this
header:


                               ui.h
                                |
                                |
          --------------------------------------------------
         |             |               |                    |
    title_bar.c     windows.c       status_bar.c        inp_win.c



So any calls to the UI are through ui.h

title_bar.c and status_bar.c are relatively trivial.

windows.c
---------

Contains a list of prof_win structs called _wins, which consist of:

    from:  A string, the name of the recipient for this chat window
    win:   An ncurses pad containing the chat contents
    y_pos: The current position in the chat window
    paged: Whether or not the pad has been paged (i.e not showing the end)

The console is _wins[0], and has a special 'from' value of "_cons".

This module contains things like a pointer to the console window, the index
of the current window being displayed, a dirty flag that indicates the current
windows should be updated next time around the loop.

inp_win.c
---------

Doesn't do much more than handle each character with inp_get_char().  Deals
with all special chars for editing the input, HOME, PAGE UP, UP, DOWN etc.

command.c
=========

When the main input loop gets a '\n', process_input() is called with the 
line of input.

This is where each command/message is handled.

jabber.c
========

All interaction with libstrophe is done here.  Contains a references to the
libstrophe objects: connection, context etc.

Functions ending 'handler' are callback handlers registered with libstrophe,
e.g. for incomming messages.

contact.c
=========

PContact represents a contact with:

    name:   The contacts JID, e.g. somecontact@server.org
    show:   "Online", "Away" etc
    status: "I'm not here right now", "At lunch" etc
