At least, from this historical record as preserved by git, it is.
In reality, this project represents a year of off-and-on development
in another git repository, and has been converted and reformatted
for (potentially) public consumption.
Particularly lacking is the Tables and other charts that make this
useful, but I need to make sure I don't violate any copyright laws, as
many of my tables were copy/pasted from digital books I own.
I realized that a DM Screen isn't really what I want. If I want
information about a particular rule or the magic school, then I want it
to pop up, and then go away.
