How to regenerate the schematic.

0- Ensure your OS handles unix-type i/o and has efficient mmap.

1- Grab layers.svg, gbi-layers.txt, gc-layers.txt, mv-config.txt, pads.txt, pins.txt, sgen.7z.  Unpack sgen.7z.

2- Optionally grab m68000-m-1.png and m68000-m-3.png from aligned,
   they're referred to by the svg but not required

3- Clone https://github.com/galibert/dietools.git
  3a- Ensure you have installed with headers and libs: lua 5.3, boost, Qt 5.x
  3b- Run make in libdie
  3c- Run make in every other directory

4- Run generate-bitmap-images gbi-config.txt
   -> this is going to generate pbms for each layer from layers.svg.
      It takes a while, 6*28Megs of files.

5- Run generate-circuit gc-config.txt
   -> this generates layers.map (2.56G) and m68000.txt (12M)

6- Go into sgen.  Change the path at the start of remap.lua, drm.lua and svg.lua as needed.
   6a- Run remap.lua to generate schem.txt
   6b- Run svg.lua to generate schem.txt and schem.svg
   6c- Create schem/tiles/{0,1,2,3,4,5,6,7} and run drm.lua to generate schem.txt and google-map-style tiles.  Grab the associated index.html in schem from the site.

7- Optionally, use mview mv-config.txt to see the circuits visual6502-style

8- Optionally, use sview schem.txt to see the schematic (-/= for zooming).
