AmiWM configuration explained

The amiwm configuration file is mostly self explanatory but will give some descriptions to assist people setting this up for the first time. Apologies for any inaccuracies as I'm typing this from memory (I'll fix things as I test later). The configuration file is stored in your home directory as .amiwmrc

Here are the parameters with descriptions;

FastQuit No - Prompt on exit amiwm
SizeBorder bottom - where the resizing handles are placed for windows
ForceMove manual - Whether windows can be moved off screen (yes/no/manual). With Manual, holding the shift key allows windows to be moved off the screen.

CustomIconsOnly yes -  uses amiga icons for applications rather than the linux icons.
IconPalette MagicWB - The color palette used (System, MagicWB, schwartz)
ShortLabelIcons yes - Whether to shorten icon labels
DefaultIcon "def_tool.info" - sets the default icon used when using CustomIconsOnly 

Example icon replacements when using customIconsOnly
The icon location I found to work is /usr/local/lib/amiwm/.

style { class "Navigator" icon "firefox.info" }
style { class "grafx2" icon "DPaint4.info" }
style { class "xpaint" icon "DPaint4.info" }
style { class "xterm" icon "Shell.info" }

This section is for each screen you want to set up.
Screen "Ubuntu 10.04.2 (lucid) - Workbench 1" - sets the title for the screen
Module "Background" "-tile -fullscreen /home/username/Pictures/tuxamiga1.jpg" - desktop image

TitlebarClock yes
TitleClockFormat "%a %b %e %Y   %l:%M %p"

Screen "Ubuntu 10.04.2 (lucid) - Workbench 2" - the second screen setup
Module "Background" "-tile -fullscreen /home/c915101/Pictures/tuxamiga2.jpg"
 
This is useful for keyboard short cuts. Only works when numlock is off
Module "Keyboard" "\
    <F1>:all:rotatescreens\
    <F2>:window|frame:iconify\
    <F3>:window|frame:front\
    <F4>:window|frame:back"

This is for the applications menu.
The format is ToolItem "<MenuEntry>" "<Command> [Arguments]"
ToolItem Separator
ToolItem "Volume" "gnome-volume-control"
ToolItem Separator
ToolItem "Apps"
       {
       ToolItem "VirtualBox" "VirtualBox"
       ToolItem "Media Player" "/usr/bin/vlc"
       ToolItem "LibreOffice" "/opt/libreoffice/program/soffice"
       ToolItem "Paint.net" "pinta"
       }
ToolItem "Tools"
       {
       ToolItem "Calculator" "gcalctool"
       ToolItem "AMOS" "sdlBasic"
       ToolItem "Deluxe Paint" "grafx2"
       ToolItem "DirOpus" "worker"
       }

I'm using defaults but you can also set up custom colors for the windows borders;
Bardetailpen "green"
Backgroundpen "black"
Barblockpen "black"
Highlighttextpen "blue"
Textpen "green"
Filltextpen "green"
Fillpen "black"
Bartrimpen "green"
Shadowpen "green"
Shinepen "blue"
Blockpen "yellow"
Detailpen "red"
