+# Generate a map from specifications on a wiki
+
+## Prereqs
+The Hexgrid modules and MWTemplate modules must be in @INC
+
+## Invoking
+Writes to STDOUT by default; use `-o/--outfile <file>` to write to a `<file>` instead
+
+The script has 2 flags controlling files generated:
+
+* `--regiondir <dir>`: If specified, also generate maps for each region and location,
+  writing them to files in <dir>. Off by default.
+* `--html/--no-html`: Whether to generate (an) SVG file(s) or (an) html file(s),
+  including logic for popups on clicks (currently half done). Makes html by default.
+
+Examples of the four combinations:
+
+1. `perl wiki-tile.pl -o output/Map.svg --no-html --regiondir output --api https://vipersgate.obscuritus.ca/api.php`
+   Creates a main map as an SVG output/Map.svg
+2. `perl wiki-tile.pl -o output/Map.svg --no-html --regiondir output --api https://vipersgate.obscuritus.ca/api.php`
+   Creates a main map as an SVG output/Map.svg and an SVG for each region and location, also in the output dir
+3. `perl wiki-tile.pl -o output/Map.html --api https://vipersgate.obscuritus.ca/api.php`
+   Creates a main map with popups as output/Map.html
+4. `perl wiki-tile.pl -o output/Map.html --regiondir output --api https://vipersgate.obscuritus.ca/api.php`
+   Creates a main map with popups as output/Map.html and an html page for each region and location, also in the output dir
+
+1 is intented to make just a map for the main page. Unnecessary if using 2.
+
+2 is intended to make a map for the main page, and for each Region, Subregion and Location page.
+
+3 is intended to be linked to and ~has~will have click-toggleable popups.
+
+4 is an artifact of the above 3 and doesn't have intended use.
+
+### Options
+Options can be abbreviated per Getopt::Long
+
+<dl>
+  <dt> `--api-url`:</dt> <dd>Base URL of the wiki</dd>
+</dl>
+Template names. Defaults to MapRegion, MapSubregion, MapLocation, MapSite.

+  <dt>--location-template-name</dt><dd></dd>
+  <dt>--site-template-name</dt><dd></dd>
+</dl>
+Formatting options.
+The tiling module supports more overrides including per region/tile granularity.
+These are not settable in the script but can be added if desired.
+<dl>
+  <dt>--border-width</dt><dd>Width of the border between hexes. Defaults to 1.</dd>
+  <dt>--border-colour</dt><dd>Colour of the border between hexes. Defaults to black.</dd>
+  <dt>--show-coords</dt>
+  <dd>
+    Include coordinates in the image.
+    Eventual goal is to have them be toggleable in the HTML output mode.
+  </dd>
+</dl>
+Output options. See above.
+<dl>
+  <dt>--html-document</dt><dd></dd>
+  <dt>--outfile</dt><dd></dd>
+  <dt>--regiondir</dt><dd></dd>
