+.woff files for SVG-in-OpenType testing
+=======================================
+
+There are three .woff files in this directory:
+ * nosvg.woff
+ * svg.woff
+ * rubbish.woff
+
+nosvg.woff
+----------
+This font is FiraSansOT-Regular, with its metrics hacked so that its ascent
+is 1000 and descent is 0. Its unitsPerEm value is 1000.
+
+It contains no 'SVG ' table.
+
+svg.woff
+--------
+This font is the same as nosvg.woff above, but with the glyphs-*.svg SVG
+documents from this directory embedded in it using the tools described below.
+
+rubbish.woff
+------------
+This font is the same as nosvg.woff above, but with the addition of an 'SVG '
+table with the contents of rubbish.txt. Its purpose is to test that SVG tables
+without valid XML are ignored.
+
+Creating the Fonts
+------------------
+The tools used here are insertsvg.py from [1] and sfnt2woff from [2].
+
+svg.woff can be recreated with:
+
+woff2sfnt nosvg.woff > nosvg.ttf
+insertsvg.py nosvg.ttf svg.ttf glyphs-*.svg
+sfnt2woff svg.ttf
+
+[1] https://github.com/edf825/SVG-OpenType-Utils
+[2] http://people.mozilla.com/~jkew/woff/
+
+
+
+Additional test fonts:
+======================
+
+svg-glyph-extents.otf
+---------------------
+
+This is a copy of Fira Sans with a simple SVG table added using the tool from
+https://github.com/rocallahan/svg-opentype-workshop. The SVG table defines four
+glyphs, corresponding to 'A' through 'D':
+
