-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
-
-It's an opaque pointer so all access to a PContact is encapsulated in this
-module.
-
-contact_list.c
-==============
-
-Currently has two purposes.
-
-First, stores a live list of online contacts.  "Live" meaning jabber.c will 
-call contact_list_add() and contact_list_remove() as it gets presence
-notifications from the server.
-
-Secondly it is used for autocompleting contact names when typing them, hence
-it stores the contact in a PAutocomplete, described later.
-
-history.c
-=========
-
-Stores a history of all input and allows navigating through it, bash style.
-
-Uses PHistory object, described later.
-
-preferences.c
-=============
-
-Deals with loading and setting preferences saved in ~/.profanity.
-
-Also allows autocomplete of previous JIDs the user has logged in with 
-(stored in ~/.profanity) by storing them in a PAutocomplete.
-
-common.c
-========
-
-Functions written for compatibility with older versions of GLib.
-
-util.c
-======
-
-Some util functions, should probably move to common.c.
-
-log.c
-=====
-
-Stores a reference to the log file, and provides functions for writing to it.
-
-Library like modules
-====================
-
-prof_history.c and prof_autocomplete.c implement a generic way to deal with 
-command history and command autocompletion respectively.
-
-The rest of Profanity uses them indirectly, via history.c for example, 
-and they know nothing about Profanity (no includes to profanity modules).
-
-These modules use opaque pointers so all access must be through functions
-exposed in their headers.
-
-The idea is that these modules could be included in other applications.
-
-The "prof_" prefix is just because they were created whilst developing
-Profanity.
-
-prof_autocomplete.c
--------------------
-
-Two types of PAutocomplete can be created.
-
-p_autocomplete_new() creates a PAutocomplete that can store strings, the
-simple case.
-
-p_obj_autocomplete_new() creates a PAutocomplete of arbitrary data 
-structures. This function must be passed function pointers of the following
-types:
-
-    PStrFunc:       A function that will get a string out of the data structure
-    PCopyFunc:      A function that will make a copy the data structure, allocating
-        memory for it.
-    PEqualDeepFunc: A function to compare two structures by comparing all members.
-    GDestroyNotify: A function that will free memory for the data structure.
