Yes.

I guess people would use YAML syntax for that today; this saves you
writing a parser by your own.

On the other hand, YAML can't be easily parsed with shell scripts – if
necessary, don't hesitate to use a script language (Python, Perl,
etc., it's basically up to you).

OK, let's delay this then.

Thanks.  However, after unpacking and clicking on

  ft-tests
  → index.html
  → ft-LiberationSerif-Regular.ttf-16-report
  → ftgrid_0002.png

(which links to `ftgrid_0002.html`), I get an empty page.

Looking around I've found the difference png – what do you think of
slightly coloring the differences?  And for comparing B/W images, I
remember that I've coloured points only in the reference image as
green and in the new image as red...
