+# FontForge script to convert its argument (some font file) to
+# woff2. The base name of the file is kept the same and a .woff2
+# extension is added. See,
+#
+#   https://fontforge.org/docs/tutorial/scripting-tutorial.html
+#
+# and the additional documentation for Generate() at
+#
+#   https://fontforge.org/docs/scripting/scripting-alpha.html#Generate
+#
+# Specifically:
+#
+#   fmflags&4 => generate a short "post" table with no glyph name info
+#   in it
+#
+#   fmflags&8 => do not include ttf instructions
+#
+#   fmflags&0x8000 => do not generate an FFTM table
+#
+#   fmflags&0x40000 => do not do flex hints
+#
+#   fmflags&0x80000 => do not include postscript hints
+#
+# And, according to python,
+#
+#   >>> 0x4 + 0x8 + 0x8000 + 0x40000 + 0x80000
