We will define the logic in a separate directory theories/tutorial. The distribution contains a version of this tutorial. During the tutorial, you will need to build the MetaPRL proof editor. The editor/ml directory already includes the tutorial files in the Makefile. After each module definition, you can rebuild the tutorial directory as follows:
% cd theories/fol % make Compiling messages
If the compilation is successful, you will then need to build the proof editor:
% cd ../../editor/ml % make Compiling messages
You can then invoke the editor with the command:
% ./mp Version message # #use "tutorial.ml";;
You can then use the editor to navigate the tutorial, as described in the page on the editor.
