This git repository contains a copy of Vengeance by Victor Gijsbers. 

On June 27 2019 Victor Gijsbers provided the source code and indicated 
it was licensed under the Creative Commons Attribution-NonCommercial 
4.0 licence (which is proprietary), or under the GNU GPL 2.0 or any 
later version, at the user's choice.

When getting a copy of the software I selected that my copy would be 
under the GNU GPL 2.0. I then took advantage of the "or any later 
version" option and upgraded it the GNU GPL 3.0. This copy of 
Vengeance is now licensed in that way.

The recommended way to get a copy of this git repository is a 
recursive clone:

    git clone --recursive https://jxself.org/git/?p=vengeance.git

This will clone all submodules recurively. If you did not perform a 
recurive clone, once you have a copy of this git repository you will 
also need the source code for the standard library:

    git submodule update --init --recursive

To compile this game you will also need version 6 of the Inform 
compiler from https://jxself.org/git/?p=inform.git

Once the compiler has been compiled and is ready for use return to 
this directory and run:

    inform +include_path=lib vengeance.inf

Or you can run the included build.sh script which does the same thing.

You will then get the story file for this game that can be run using 
any appropriate Z-Machine interpreter, such as Frotz. Your GNU/Linux 
distro probably has that packaged already for easy installation.
