 # PNG from SVG (via Inkscape)
+# This is weird: --export-pdf writes the output image exactly where you tell
+# it, whereas --export-png seems to write it relative to the original image??
+# So if the original is in images/foo.svg, then --export-pdf=images/foo.pdf
+# will create images/foo.pdf, but --export-png=images/foo.png looks like it's
+# trying to create images/images/foo.png. --export-png=foo.png will create
+# images/foo.png.
+#
+# ?!?!?!  Argh. Bug report submitted to Inkscape.
