To package abioword using NSIS

you need the NSIS program, 
specifically the slightly changed version kept by abiword.  The Nullsoft version will function exactly the same but the abiword version will be superficially slightly different.  

you need the script (.nsi file)
you need the 2 bitmaps and the abiword icon.  

Install Abiword using the existing installer.  put the scripts and icons in the Abisuite directory and compile the script.  
The current script is only for demonstration purposes and MUST be changed to install abiword proplerly.  

note
The Licenses of the Installer should DEFINATELY NOT be changed, unless Nullsoft change the license.  Any patches must be of the same license.
