Ah, thanks for this hint!

Text::Diff and Text::Diff::HTML, I see the following differences:
String:Diff allows you much more flexibility but also expects from you
way more configuration, i.e. you seem to always have to give opening
and closing HTML tags for additions and removals explicitly. At least
the synopsis looks like getting something comparable to Text::Diff::HTML
with String::Diff would be quite some configuration work.
Text:Diff::HTML already knows about practical HTML tags (the same as
suggested in String::Diff's examples :-) for this purpose so you only
need an appropriate CSS. There's one in the distribution included, so
the only thing you have to yourself here is calling Text::Diff::diff
on two strings, say yoyu want HTML output and include the CSS.
Short said, String::Diff is extremely flexible and tedious, Text::Diff::HTML
does only one thing, but DWIM and out of the box. String::Diff seems
more a framework, Text::Diff::HTML only a renderer (for Text::Diff).
And I actually was looking for a Text::Diff renderer for HTML output
as we already use Text::Diff, partially via Test::Differences.
So despite I am happy about the alternative and despite I see the
similarities, I also see that String::Diff can't really provide what I
was looking for. So I'd say, I go on.
But yes, we should check the descriptions, the long as well as short
ones and highlight the differences.
Regards, Axel
