+Introduction
+------------
+
+This repository contains a program to generate a new board for
+Pandemic Rising Tide. The board is gameplay-identical to the
+original, but the graphics are entirely abstracted and the board is
+intended to be easier to play on.
+
+
+Use
+---
+
+`make' will generate[1] many PostScript and PDF files. You probably
+want to use the PDFs. Specifically:
+
+If you have a printer capable of A3:
+
+ board-pa3-bPageB.pdf on A4
+ board-pa3-bPageMT.pdf on A3
+
+If you have a printer capable of A4:
+
+ pa4-bPageB } print one
+ pa4-bPageM } of each
+ pa4-bPageT } on A4
+
+If you have a printer capable of A1 and want something you can fold in
+three to paste onto a Z-shaped board to fit into the original A4 box:
+
+ pa1m-bPageP on A1, and cut at the indicated marks
+
+If you have a printer capable of A1 and don't need that slight size
+reduction:
+
+ pa1-bPageP on A1, and cut at the indicated marks
+
+If you are in the US and can't print on sensible international paper
+sizes, read this

+and feel free to send me patches.

+
+[1] Dependencies
+-----------------
+
+You will, notably, need a working copy of plag-mangler, which is a
+planar graph manipulation and layout program I wrote for this project.
+ https://www.chiark.greenend.org.uk/~ianmdlvl/plag-mangler/
+
+It has, in turn, quite a few dependencies.
+
+The other direct dependencies of this repository should be readily
+available on your distro.
